WA1: Synopsys User and Tutorial Sessions
WA1.1 Tutorial: Zebu Overview, Easier HDL Cosim, Productivity Techniques
Synopsys
In this tutorial you will receive an overview of the the Zebu platform and an introduction to the verification and validation use cases afforded by this platform. You will learn how to enable HDL Cosim to improve simulation performance and the nuances of getting the best results.

WA1.2 User Paper: Zebu Transactors for Verification & Validation
Karthikeyan Rajamanickam - Texas Instruments
Our main focus is on pre-silicon verification and validation capabilities adopted using Zebu Transactors at different levels, bridging the gap between simulation and silicon. Transactors also aid in areas on porting the ASIC RTL to pre-silicon with minimum modifications. Given its non-intrusive instrumentation capabilities, it helps in collection of statistical data for profiling when system runs at a reasonable speed when simulation is an impossible task. ZRM provides easier access for data pre-processing adding value to architecture evaluation. The session will also cover a use model for functional verification to analyze complex sequence of events and enable triggers/signal events. On to verification automation support, we mimic the FPGA used along with silicon to provide test support and additional functionalities to the RTB using a transactor, which works seamlessly compared to hardware connectors on silicon-based test set-up.

WA1.3 User Paper: Innovative Approach to Overcome Limitations of Netlist Simulation
Prodip Kundu, Pankaj Singh, Narendran Kumaragurunathan, Meera Mohan - AMD India Pvt. Ltd
One of the biggest challenges in running gate-level simulations is to quickly find or debug the source of the failing node. This paper elaborates on a proposed automated flow using Verdi APIs to enhance the debug capability during the gate-level simulation debug to get to the root cause of the failure. This automated signature assignment-debug process helps ensure the team is focused on solving critical mis-compares and thus meeting the schedule. In this paper we will share this flow, based on several bugs which we found during the netlist simulation of a real design.

WB1.1 User Paper: Addressing Signoff Timing Quality and Cycle Time Challenges in High Performance Processor Designs
This paper showcases the flows and methodologies developed to address critical challenges and improve the cycle time/efficiency of timing closure in High Performance Processor designs. We enabled over-night flat analysis for large hierarchies of the design using the tools runtime/capacity, greatly reducing the scope of hierarchical model generation/validation/usage. Along with the integrated noise analysis, this brought a significant improvement in overall cycle time. From a feature standpoint, a MIS modeling approach for hold closure was implemented. We use a custom rule-based ERC/Timing quality checker, to meet stringent quality and timing requirements for CPU designs.

This paper will discuss native ECO fixing and what-if capabilities which enabled a push-button setup/hold/drc fixing solution in the closing stages of timing closure as compared to more effort intensive manual/custom fixing solutions. We are also evaluating an improved hierarchical solution to replace traditional block modeling for reducing cycle time and use AOCVM for pessimism reduction on high-speed paths.

WB1.2 User Paper: Novel Approach to do Multi Voltage Signoff using SMVA
Ish Chadha - NVIDIA
Low power brings new challenges in form of MV domain & dynamic voltage and frequency scaling (DVFS). Traditional STA for handling single power domain linked signoff vs. covering all MV/DVFS/use-cases brings its own challenges. To cover challenges signoff flow based on link per instance and derate were developed to cover MV/DVFS/use-cases scenarios. However with an increase in the number of voltage domains and use cases the number of possible combinations for signoff has increased dramatically. In-house MV signoff flows can’t handle such large of scenarios without compromising on accuracy or incurring a large runtime penalty. Hence alternate approaches that could scale with future needs had to evaluated/developed. In this paper we will go through an SMVA based MV sign off flow that has been deployed on a recent complex mobile chip. The paper will discuss the challenges and advantages offered by SMVA. It will also discuss some of limitation, enhancements/recommendations for future.

WC1.2 User Paper: FineSim for Complex Mixed-Signal SoC Verification
Anmol Mahajan, Amit Kumar Singh, Karthik Sundararaj - Analog Devices, India, Vivek Sharma - Synopsys
With ever increasing size and complexity of mixed-signal SoC (System on Chip) designs and aggressive time-to-market constraints, there is a need to uncover any potential functional and performance issues in silicon much before tape out.

In this paper we will discuss the application of FineSim and its value addition to mixed-signal verification and sign-off for two large mixed signal SoCs. The methodology used and challenges faced in deployment of FineSim towards the same will be covered. We will present details on critical power-up issues in one of the designs uncovered by the full chip simulation using FineSim, eventually avoiding a potential silicon re-spin. We will present correlation for power numbers obtained in simulations with silicon measurements for the other design. We will also discuss future scope applications of FineSim for post layout effect simulation, dynamic voltage drop and electro-migration analysis at block and chip level.

WC1.3 User Paper: Custom Routing Flow Enablement for Advanced Nodes
The increasing complexity of manufacturing rules has made the often hand crafted custom digital and analog layout process very time intensive. At advanced nodes, electrical and manufacturing concerns have introduced specific and inconsistent rules. This demands a great degree of automation in custom routing to improve the layout turnaround time. Satisfying the analog designers requires a host of special requirements such as support for differential pair, buses, RC matching, and shielding in addition to a standard gridless routing.

This paper focusses on the rolling out of a custom routing flow using the Titan Shape Based Router (SBR) for advanced nodes. The core router with open access database support has been configured with advanced DRC rules to support the complete set of manufacturing rules. Constraint-driven routing flow with support to bus routing, differential pair, tandem/coaxial shielding, multi-layer length matching and RC matching has been enabled.

WD1.1 User Paper: Increase ATPG Throughput While Reducing Care Bits: Optimizing Transition Fault Patterns
Mudasir Kawoosa, Rajesh Mittal, Prakash Narayanan - Texas Instruments, Surya Samavedam - NVIDIA
Test time reduction for application of scan patterns using an ATPG tool can be achieved in several ways. Examples include using scan compression to increase the number of internal STUMPS while reducing the STUMPS length, increasing the internal shift frequency, reducing the idle time between the shift and capture phases, etc. All of these techniques are well understood and have been exploited in design, DFT and ATPG tools. In this paper we propose a new approach towards test time reduction with scan patterns. This is based on reducing care bits that need to be constrained during transition fault pattern generation so as to reduce the effect of constraints bits and thereby achieve more coverage and reduced pattern count.

WD1.2 User Paper: Effective ATPG with Hierarchical DFT Methodology for SoC
Seema Shareef, Soham Roy, Ashwini Shankar - Wipro Technologies
With growing design complexities, the general way of flat DFT methodology is not practical any more. Flat designs are prone to larger simulation run times and pose difficulty during diagnosis and debug. In this paper, a hierarchical approach to DFT is presented to tackle the problems encountered when incorporating DFT to SOC designs. We propose a hierarchical DFT methodology in conjunction with reduced pin count test. We show that it is feasible to achieve better ATPG results with a comprehensive hierarchical DFT for System-on-chip devices.

WD1.3 User Paper: Sharing Scan-Ins For Similar Cores
Deepak Agrawal, Daryl Pereira, Sanjay Shinde, Aanand Venkatachalam - LSI India
As the technology is shrinking the SOCs are growing in density and gate count. This creates challenges regarding the testability and more importantly the test cost. Almost all big SOCs have physical hierarchies for implementation. Also many of today’s SOCs have multiple instances of a few modules. This gives an opportunity to optimize test cost. This paper demonstrates how we handled the scan implementation for our design. We also addressed the complexity related to multiple levels of physical hierarchy as the block is instantiated inside another physical hierarchy. We will discuss how we used the shared scan-in’s feature of DFT-MAX for the block instantiated multiple times. Finally we will share how this approach helped reduce the test data volume/ test pin requirements and still retain full observability on the scan output.

WD1.4: New, Innovative Test Technology to Reduce the Cost of Quality
Rohit Kapur - Synopsys
About a dozen years ago, one DFT methodology—scan compression—addressed the fundamental need to lower test costs while maintaining high quality and high productivity. Although DFT methodologies have since kept pace with design and test requirements, in a few years SoCs likely will be an order of magnitude more complex than today’s designs and contain hundreds, if not thousands, of cores. This session will focus on exciting advancements in DFT to meet the test cost, quality, and design closure requirements of the next generation of SoCs.

WA2.1 User Paper: X-Propagation - Improving the Methodology in Uncovering X-optimism Issues
Ashish Gogia - Cisco Systems India, Shekhar Basavanna, Vasudev Srinivasan - Synopsys
The gate level simulations (GLS) play a critical part in the verification cycle to catch the X-optimism issues missed during RTL simulations, though it could still leave some functional bugs due to its inherently non-exhaustive nature. This paper talks about VCS’s new technology X-propagation (X-prop) and our experience with it and how it helped in mitigating some of these concerns and improving the overall process. The paper talks in detail about the two modes of Xprop feature – T-merge and X-merge, and their usage in uncovering potential design bugs. We will also explore how X-merge mode simulation can be used as an alternative for GLS zero-delay simulation and help in overall productivity.

WA2.2 User Paper: Certitude for Functional Safety
Deva Phanindra Kumar,Ranganayakulu Sri - Analog Devices Inc.
Functional Safety is becoming increasingly important in the automotive market or any other safety critical market. Better ASIL certification provides an extra edge over competition. This paper discusses simulation techniques which will help to improve functional safety and in diagnostic coverage analysis using Certitude. Certitude is not used for functional qualification purposes in these simulations but as fault injection and fault coverage tool. The proposed technique is being tested on gyroscope and accelerometer project and a case study of the same is presented in this paper.

WA2.3 User Paper: Reconfigurable Verification Environments with Discovery VIP & Reusable Test Cases Using SystemVerilog DPI
Yugandhar Kadiry, Naresh Duriseti - Mindspeed Technologies, Viswanath Daita - Synopsys
In this paper we will introduce a SystemVerilog-DPI based approach to create sub-system level test cases in C language. Through this we can achieve testcase re-usability at chip top level. With this approach designers can also write verification methodology independent test cases. This will immediately help in reduction of resource usage and a shorter verification cycle. We used this methodology to verify a sub-system containing Ethernet IP.

A reconfigurable verification environment is built using AMBA and Ethernet VIP for sub-system level verification. The verification environment is divided into a reconfigurable AMBA-based system and an Ethernet VIP-based system and a communication block. The paper discusses our approach, including how we could reuse the Ethernet VIP subsystem at chip top level to run the same sub system level test cases at chip top level. We will propose guidelines on how this approach can be used for projects across subsystems with different IP.

WB2: Synopsys User Session
WB2.1 User Paper: Handling Non-monotonic Delays in Static Timing Analysis
Lisha Krishnan, Mohan Sultania, Debashis Sarkar - Cypress
STA methodology, being graph based, propagates the 'worst slew' at signal merging points. This means propagating the slowest transition for setup and fastest transition for hold timing based on the assumption of linear delay value dependency on input transition time.

When the linear model assumption is broken— for instance when the propagation delay decreases with increasing transition termed as non-monotonicity (as in the case of some Cypress libraries at higher transition times)—the 'worst slew' propagation results in best delays for setup and worst delays for hold. This becomes an optimistic analysis and leads to false positives in STA and silicon failure later on. Here we describe the methodology used to identify such paths and ensure correct analysis is performed

WB2.2: TAT Improvement in Signoff Extraction using SMC Flows
Gopinath Devarajan, Dan Prevedel - LSI
Simultaneous Multi Corner (SMC) flow enables extraction of parasitics for multiple process and temperature corners in a single run and provides significant runtime efficiency when compared to standalone extraction without sacrificing accuracy. The runtime efficiency of this flow increases with the increase in number of parasitic corners at which designs need to be signed-off. This paper quantifies the runtime benefits that can be achieved with the SMC flow and the accuracy and timing correlation results.

WB2.3 Tutorial: Handling of Advanced Technology and Process Challenges in Parasitic Extraction using StarRC
Synopsys
Advanced technologies and processes offer great benefits but also bring a lot of challenges to the parasitic extraction domain. This tutorial will cover modeling and extraction of FinFET devices, flows to handle Double Patterning and best practices for performing extraction with StarRc to optimize performance and improve productivity.

WC2.1 User Paper: Determining PLL Clock Jitter Characteristics Using XA-VCS Mixed-Signal Simulations
Ratheesh Mekkadan - AMD
Determining clock Jitter characteristics of the PLL is important as this could cause setup and hold time violations for downstream digital logic clocked by the PLL. This could also lead to functional failures and/or performance degradation. Current methods of running transient simulations using circuit simulators for jitter characterization is extremely slow. This problem is compounded when simulations have to be run across multiple PVT Corners.

Mixed signal simulations using XA-VCS is the solution for this, especially while determining the contribution of different blocks within the PLL to clock jitter. For example, a mixed signal simulation setup of the PLL with its analog blocks (PFD+CP+LPF+VCO) in spice netlist format and digital blocks (Feedback Divider, Post Dividers, State Machines, Clock Muxes etc.) in HDL can be used to analyze the contribution of analog blocks to jitter. This paper covers mixed-signal setup, measurement techniques and performance (Cosim vs. All transistor sim) comparison.

WC2.2 User Paper: Dynamic Electrical Rule Checking (ERC) Capability in FineSim to Avoid Hot-Spots & Achieve Low-Power Specification
Mithun Kumar, Ashwin Nyamati - Microchip Technology India Pvt Ltd, Vivek Sharma - Synopsys
The Dynamic ERC capability or .chkdcpath feature in FineSim helps to catch dc current consumption paths. And with zgate switch enabled, the leaky path caused due to floating gates gets revealed for fixing the same. These fixes are needed to avoid hot spots or current surges in power-down mode. Without this, the issues would only be caught by testers during chip silicon testing, requiring re-spins to meet low power spec. This paper explains how FineSim’s Dynamic ERC verification methodology deployed in Microchip has helped to meet low power specification. It demonstrates the leaky paths caused due to Hi-Z Gate with real sample circuits, and also suggests possible fixes that can be implemented with ease by designers. Finally it talks about how FineSim’s performance and flexible Digital UI/cosim capabilities has helped improve the coverage by allowing both analog & digital groups to perform the Dynamic ERC checks independently, at both macro & full-chip level.

WC2.3 User Paper: EMI & SSO simulation on board: Modelling, Analysis, And Design Solutions
Akhilesh Mishra, Prabhat Ranjan,Yagya Dutt Mishra - STMicroelectronics
Board-level I/Os’ signal integrity and conducted EMI have become a critical concern for high-speed circuit designers, and a major cause of performance and reliability degradation of modern electronic systems. In this paper we investigate the impact of Simultaneous Switching Output (SSO) noise and propose a methodology for SSO analysis and mitigation based on IBIS 5.0 that can be seamlessly integrated into an industrial design flow. Experimental results obtained on an automotive microcontroller demonstrate the effectiveness of the proposed approach

WD2.2 User Paper: A Methodology of Automation of SoC Validation using FPGA
Debabrata Ghosh, Felix Paul - Infineon Technologies
Post Silicon Validation (PSV) is the key task to ensure needed quality is achieved in silicon before the product reaches the customer. Hence, PSV necessitates stressing the system and its internal components in terms of Use Case scenarios. Also, with more and more sophisticated requirements, the complexity of the chip is increasing day by day, and achieving time to market is pivotal for product and business success. The proposed approach of an FPGA-based solution helps to accelerate the validation cycle by automation. The objective of the effort is to provide an efficient solution that will reduce the manual effort and increase the reliability of the test setup. The design should also provide the flexibility to change the configuration on-the-fly. The paper presents a method of changing FPGA glue logic with the help of three pins connected and controlled by the microcontroller.

WA3.1 User Paper: AFE Verification - A Novel approach for Mixed Signal Verification
Neeraj Chandak, Nitin Goel, Yogesh Mittal - Freescale Semiconductors India Pvt Ltd.
As the industry is moving towards lower nodes, the integration of analog, RF and mixed signal design components in the same SoC is increasing. While the verification of the digital IPs is able to scale up viz-a-viz simulation speed and quality through constraint-driven random verification methodology, analog verification still suffers from a lack of this type of infrastructure. The conventional method for verifying the digital portion of the design (as behavioral or black box) and analog portion separately (SPICE) is not sufficient as the main verification complexity lies in checking the level of interaction between the digital and analog portions. This paper presents a novel methodology for the verification of analog and mixed-signal circuits using HVLs which improves reuse and enables automation to improve Quality Control and reduce Time to Market for SoCs.

WA3.2 User Paper: Generic RAL Infrastructure to Address Register Verification Challenges
Sreenivas Machavaram, Anil Kumar Sabbineni, Prashanth Srinivasa - LSI
Our approach is about a generic RAL (Register Abstraction layer) translator which is built using the powerful features of VMM for providing non-blocking access to every master. We would also mention how the Endianness switching is supported in the RAL translator so there is no need to maintain two sets of the System RDL, RALF or RAL model files for both the Endian modes. This paper also showcases how the RAL translator can be re-used at any level of verification and provides flexibility for any number/kind of interface translations. This translator has built-in support to address all the following challenges
  • Multiple masters accessing same slave simultaneously using a single RAL model
  • Slave has different address views for all Masters
  • Sampling the register access coverage from each master using the single RAL model.
  • The Endianness of the system is configurable.

WB3.1 User Paper: The Last Microwatt - Challenges in Pre Silicon Power Estimation for Low-Power SoCs
Accurate pre-silicon power estimation is an increasingly critical requirement in developing high-performance and ultra-low-power SoCs. Wide adoption of the UPF standard has enabled efficient design and verification of complex low power designs. However, to effectively balance the tradeoff between performance and power, it is also imperative to fine-tune CAD flows and methodologies to estimate both leakage and active power accurately up to the last microwatt. In this paper we discuss some of the key challenges that we encountered in improving the accuracy of pre-silicon power estimates, and methods we used to overcome them for low power designs. Resolution of these challenges resulted in considerable improvement in the accuracy of our Pre-Silicon power estimation.

WB3.2 User Paper: Method for Collapsing Multiple Modes Timing Constraints
Rajkumar Agrawal, Vivek Manikandan LSI India Research & Development Pvt Ltd
With increases in design complexity the number of STA modes has shot up. In addition, the newer process nodes have introduced a higher number of new PVT corners. These factors have contributed to an explosion in the number of scenarios for which static timing analysis (STA) needs to be performed. This has a major role in the timing signoff TAT and has resulted in a bottleneck in the design flow. One of the possible ways to handle this issue is by collapsing the number of STA modes using the approaches described in this paper. The optimal number of STA modes can be decided by user. In our implementation, we considered 3-5 as the optimal number for signoff STA modes. We also discuss the native solution for merging modes that has been made available in PrimeTime.

WB3.3 Tutorial: Mode Merging using PrimeTime-GCA
Synopsys
In designs using advanced deep submicron technology nodes, the number of multicorner-multimode analysis scenarios has increased dramatically. One approach to address these problems is to reduce the number of scenarios by manually combining SDC constraints from related input modes to generate a merged superset of constraints. However, this method is cumbersome and error-prone with the growing number of modes and can cause loss of accuracy and the generation of incorrect SDC constraints.

In this tutorial we will discuss the new feature in PrimeTime-GCA that enables automated mode merging. With this capability, you can automatically analyze and merge the input mode design constraints into a reduced set of constraints. You can then use the newly-merged design constraints to speed up timing analysis and drive ECO runs in place of the individual input mode constraints, which significantly reduces computing resource requirements with minimal impact on accuracy and runtime.

WC3.1 User: On Chip Adaptive Voltage Scaling to Minimize Dynamic Current Consumption
Kumar Abhishek, Sunny Gupta, Nitin Pant, Manmohan Rana - Freescale Semiconductors
Conventionally, SoCs are timed for worst case performance. This means that critical paths are timed to operate correctly at minimum voltage and slowest devices, which can be described as the PVT (Process, Voltage, Temperature) corner. However, most of the time the chip operates in much better conditions, in terms of the three PVT parameters. Therefore, in such conditions, even the most critical paths in design will have sufficient positive slack.

We propose a solution by which we not only have enough timing slack to ensure timing is met across PVT but also reduce power consumption by making the design work at an optimal voltage by dynamically modulating the output voltage of the on-chip regulator feeding the SOG.

WC3.2 Tutorial: Characterizing Memories and Black Boxes: Belling the Cat
Mohamed Filzer Kummudiyil - Synopsys
Characterizing memory instances is essentially a demanding task, with its size, architecture, parasitics and features testing the limits. Characterizing complex IOs and Macros, on the other hand, poses an equal challenge with their size, complexity or black box design, operational modes, complex sensitizations and SPICE mandate requiring extreme customizations and flexibility. This tutorial talks about innovative solutions and approaches to tame thesse challenges, and churn out libraries even faster - at uncompromised accuracies.

WD3.1 User Paper: Simplify Secure System Validation and Development: HAPS Prototyping Case Study
Yuvaraj Ghorpade - LSI India
The hardware IP blocks which are used in secure systems have specialized data protection where the data paths are kept point to point without intermediate tap or debug points. The inherent 'INACCESSIBLE' nature of these IPs is a main challenge to build the pre-silicon validation environment. This paper is a real life case study in which the Synopsys HAPS platform was used to enable back-door entry points to simplify validation of these highly secure hardware IPs or systems.

WD3.2 User Paper: Challenges in Mapping Multi-core A15 ARM Processor on FPGA

The Role of Intelligent Silicon in Addressing Data Deluge Gap
Raman Santhanakrishnan - LSI India R&D Pvt Ltd
We live in a data-centric era, a world where numerous and simultaneous mega trends like social platforms, smart clients, mobile broadband internet, video and the cloud are resulting in exponential growth in the creation, storage and sharing of data. As machines begin to talk to machines, this trend is accelerating even further. The resultant "data deluge" gap created by this trend can only be successfully addressed by "Intelligent Silicon". Silicon that has been a key catalyst for innovation, the foundation for cloud infrastructure (includes client devices, mobile network and the datacenter) enabling breakthrough processing speeds, dramatically reduced power and size, tremendous cost savings, efficient data transfer and storage. What does "Intelligent Silicon" mean? What are the major requirements on such silicon and how are those met? As the relentless pressure on cloud infrastructure continues, how do we design and deploy intelligent silicon that addresses these future needs? What kind of design methodologies, IP and technology requirements are unfolding in front of us to meet them?

In this presentation, Santhanakrishnan Raman talks about these important drivers and describe how we are positioned to deliver the intelligent silicon that the data-centric era deserves.

TA1.1 Tutorial: Design with FinFET & Double-Patterning, a Brief History of the Future
Synopsys
While planar transistors have worked well from 100 microns down to 20 nanometers, revolutionary, non-planar transistors such as FinFET offer superior attributes and demonstrate much better results in terms of performance, static and dynamic power at 14 nanometers and beyond. However, although FinFET is considered as the most promising device for emerging technology nodes, it introduces new design complexity for IP development, electrical simulation, RC extraction, and physical verification. Even interconnect is undertaking a revolutionary evolution: the last pitch manufacturable using immersion lithography with single exposure is 80 nanometers; starting at 20 nanometers, double-patterning is required as we wait for EUV availability, and might be replaced by triple- and even multi-patterning at 14 nanometers and beyond; like FinFET, double-patterning introduces new design complexity for IP development, and physical implementation and verification. Please, join this session to hear what EDA is doing to hide unnecessary details, whilst enabling designers to get the most out of these emerging technology nodes.

TA1.2 User Paper: Physical Design Challenges of a High-performance FPGA in 22nm Process Technology
Aravind Karanth, Veena Radhakrishnan, Madhusudan Rajagopal, Namit Varma - Achronix Semiconductor Corporation
This paper describes the physical implementation and verification challenges of a 432mm2, 6 billion transistors, high-performance FPGA chip, designed in 22nm 3-D tri-gate process technology. With a large central macro surrounded by multiple high-speed interface blocks with highly skewed aspect ratios and a channel dominated fullchip, the implementation challenges were many. The fullchip, as well as the blocks, had multiple synchronous clocks leading to very tight clock balancing requirements and semi-custom CTS implementations. High block-level port counts led to innovative routing solutions at fullchip. Blocks with huge feed-through data & clock busses, with perpetually changing IO timing requirements, were a major challenge for timing closure. The paper also goes into details of the fullchip physical integration & physical verification challenges faced, given the large die size and 22nm tri-gate transistor technology.

TA1.3 User Paper: Floorplanning is an ART and with DFA You are an Artist!!
Hardeep Singh , Veena Venugopalan , Sarvesh Verma - LSI India Research and Development Pvt. Ltd.
Design complexities have unearthed a detrimental dependency of quality-of-results on the design’s initial Floorplan. With the classification gap among designers as RTL and physical designers, the latter generally do not have visibility into the design’s high-level Data Flow model, which has a potential impact on floorplan. Therefore, physical designers can squander precious time and resources to bridge this gap and understand how to arrive at an optimal floorplan, eventually impacting their efficiency and design cycle time. Synopsys bridges this Data Flow model awareness gap , with its Data Flow Analysis (DFA) technology, which equips and empowers physical designers with data flow knowledge through a set of analysis and exploration tools for tasks like macro placement, macro interactivity with logic and IO resulting in quicker and optimal floorplans. This paper highlights the 3X design cycle time gain and improved QoR, using DFA technology on our Macro & Memory intensive designs over conventional methods.

TA2.1 User Paper: Optimization Techniques for Designing a Channel Dominated High Activity Multimillion 500+Sq mm Chip
Anurag Mishra - LSI R&D (India) Pvt. Ltd. Vineet Kumar Kothari - Synopsys
With innumerable applications becoming viable through chip design, we’re seeing an inception of complex and efficient designs on board. For such uniquely challenging designs conventional techniques alone may not offer optimal results. This necessitates innovative solutions to meet design closure criteria with minimum TAT.

The design under discussion measures around 500 sqmm, has 120M+ gates with upf and 55 partitions with intricate intercommunication between them. Result: A channel dominated floorplan with multiple nets of varying length traversing through the channel. This in turn, contributed to significant increase in chip power. Also, higher signal interconnects demand larger DECAP area to meet IVD requirement. Hence, the design needed out-of-the-box optimization techniques to deliver better QoR and run-time, while simultaneously meeting other specifications. In this paper, we will discuss the challenges posed by the designs of such size and complexity and elaborate on pioneering optimization techniques to address such challenges

TA2.2 User Paper: In-Design 20nm Physical Verification Closure Within ICC Using ICV
Siddika Gundlur, Hemasundar Pethakamsetty - AMD India Pvt Ltd.
As technology scales down to 20nm , the number of complex DRC including the emergence of DPT rule checks to achieve acceptable manufacturability are increasing, leading to an increasing number of violations after routing phase. Fixing post-route violations manually is time consuming thus affecting the tape-out schedules. In-design physical verification of IC Validator brings the power of full signoff physical verification constraints into the design phase without imposing time-consuming stream-in and stream-out process. Using in-design PV, DRC and manufacturing issues are caught much earlier in the design cycle, eliminating late-stage surprises close to tape-out. IC-Validator’s pattern-matching technology eliminates the need for convoluted rules and, with almost zero runtime penalty per pattern, it significantly speeds up the time to achieve manufacturing compliance. This paper presents how In-Design physical-verification and fixing with in ICC-ICV interface at 20nm, helped to reduce TAT between Physical-Implementation and Signoff Physical-Verification phases thus reducing tape-out schedule.

TA2.3 User Paper: Multi-Pronged Approach to Address Nanometer Physical Verification Challenges
Complexity in nanometer-processes requires radical improvements over the way physical-verification was handled earlier. Physical-verification tools need a different approach to handle increased complexity in DRC, LVS and reliability checks. Physical-verification approaches that were successful earlier are no longer scalable by merely increasing compute infrastructure.

Topics covered include:
  1. New features that were brought into layout-verification to handle complex nanometer rules
  2. High-level language features to achieve higher programmability including API, remote and user-defined functions.
  3. LVS ease of use with multiple connect sections, user interface for device extraction, improvements in dimensional, ERC checks
  4. Runtime and improvements in debug assistance in DRC and LVS run environment.
The paper also discusses the mysql error database and features in detail to support better debug. Overall, this paper covers different aspects incorporated into advanced physical-verification tool to overcome sign-off problems caused due to process, design complexity in sub-micron design nodes.

TB3.1 Tutorial: Certitude for Functional Qualification
Synopsys
Verification engineers continually struggle with questions related to verification effectiveness. Do my test scenarios exercise the functionality sufficiently? Is my checker and assertion infrastructure complete? Traditional coverage techniques only determine if you’ve executed all lines of code or whether you’ve exercised all important functionality that you have defined. This analysis may not be sufficient, and there is no objective measure of "completeness". This session will explain how Certitude Functional Qualification augments traditional coverage to provide unique insight into the quality of simulation and formal verification environments. Certitude's proprietary mutation-based process inserts "artificial bugs" or faults into the design and measures the ability of the verification environment to detect these faults. The results of this process provide an objective measure of overall verification quality and identify specific holes and weaknesses that can allow RTL bugs to slip through the process.
