Boosting Productivity and Robustness in the SysMoore with a Triple-play of Hyperconvergency, Analytics, and AI Innovations

Tuesday, October 5 | 09:00 AM PDT

The SysMoore Era can be characterized as the widening gap between classic Moore’s Law scaling and increasing system complexity. System-on-a-chip complexity has now fallen by the wayside to systems-of-chips with the need for smaller process nodes, and multi-die integration. With engineers now handling not just larger chip designs but systems comprised of multiple chips, the focus on user productivity and design robustness becomes a major factor in getting designs to market in the fastest time and with the best possible PPA. Combining a hyperconvergent design flow with smart data analytics and AI-based solution space exploration provides a huge benefit to the engineer tasked with completing these systems. In this presentation Shankar will outline the challenges and the road to a triple-play solution that gets design engineers out of their late inning jams.

Fast and Cost Effective Analysis to Improve System Reliability

Ghani Kanawati, Arm

Reliability, availability and serviceability is a major concern for cloud applications. Many semiconductor and system companies put emphasis on adding hardware duplication, a costly solution to detect and mitigate failures. A deep analysis of the design can identify the portions of the design that can cause the system to behave unpredictably in the presence of soft errors. Statistical analysis based on probability of error propagation in the design can be performed in large complex systems such as the ones in cloud applications before any testbenches are available. We will present our findings based on the static analysis approach used in TestMAX FuSa to quickly identify the registers most vulnerable to soft errors early in the design development.

Physical and Timing-aware RTL Power Exploration

Wayne Szeto, Senior Component Design Engineer, Intel Corporation

One of the biggest problems with RTL power estimation is accuracy comparing against sign-off power. If the estimation is not accurate, designers lose confidence in the tool. There are multiple factors that make power estimation at the RTL level challenging. Clock tree modeling is not accurate at the RTL level because CTS is only done during implementation. Clock tree power contributes up to 30% of the overall power for some workload. Estimation without timing and physical awareness also causes power miscorrelation. Additionally, glitch power cannot be accurately calculated without timing information. Finally using different synthesis engines between RTL power estimation and implementation also contributes to miscorrelation. PrimePower RTL addresses most of the challenges we face today. The tool is timing and physical aware, models clock tree topologies as actual implementation, and glitch power can be calculated with delay-shifting. It also uses the same fast compile engine as the construction tool, Fusion Complier. This presentation covers power estimation results from two projects, including glitch power analysis, and ways to explore power reduction opportunities.

11:35 - 11:55 AM

Utilizing RedHawk Analysis Fusion to Relieve Voltage Drop Issues at 5nm and Below

Jinwei Zeng, Senior IC Backend Engineer, SaneChips​

With the downscaling of standard cells at 5nm and below, the risk of increasing local power density and voltage drop on the PG network has attracted a lot of attention. In this presentation we review how the Synopsys RedHawk Analysis Fusion power integrity flow enables Sanechips to reduce voltage-drop violations in advanced 5nm and 3nm designs with minimum impact to timing QoR. Potential PG network issues are detected early during implementation, followed by optimized voltage-drop-aware placement, CTS, and routing in Synopsys Fusion Compiler. With the application of the RedHawk Analysis Fusion flow, the voltage drop issues on PG network can be revealed and fixed early, and thus significantly reducing the turnaround time for the design cycle.

11:55 AM - 12:15 PM

It’s a Dynamic World – Managing Dynamic Power with Synopsys’ End-to-End Solution for Energy Efficient Design

Godwin Maben, Synopsys Fellow, Strategy & System Architects Group, Synopsys

Power-Aware ATPG Using Sign-Off Models

Mediatek
Synopsys

Power-aware ATPG has been a staple of the IC manufacturing community for many years. Historically, relying on weighting functions to drive the metrics of pattern generation has served the community well to help compose pattern sets that did not cause undue IR-drop during pattern application which could lower device yield. But larger reticle sizes, on-chip variation, and a refined focus on yield have led to more advanced methodologies. This presentation illuminates promising automation developed in collaboration with MediaTek, which combines the sign-off models from PrimePower with the fast calculation algorithms of TestMAX™ ATPG to generate fewer patterns with higher coverage that don’t exceed the IR-drop limits.

11:35 - 11:55 AM

Cell-aware Defect Detection- Robust vs. Non-Robust Detection

Ruifeng Guo, Sr. Staff Engineer, Synopsys

The standard approach is to target defects between cells. These “inter-cell faults” are always assigned to the input and output pins of cell instances. Cell-aware fault model is used to find the physical defects that originate inside the cells. The two ways of detection are Robust and Non-Robust. In collaboration with Elmos, this presentation compares the cell-aware test coverage data on over seven designs.

Accelerating PPA Improvements with Scalability using DSO.ai

Milind Mahajan, Intel
Corporation

Achieving predictable convergence for RTL2GDS design is heavily dependent on design input collaterals quality and is susceptible to changes in RTL, floorplan, stdcell/EBB libraries, design constraints etc. This problem gets harder for designing multi-million instance SOC/IPs being developed on leading process nodes and includes new SOC/IP architectures where changes in RTL, floorplan are large and constant. Using ML/AI based design optimization through DSO.ai, we can simplify optimization of key metrics and explore various tradeoffs. DSO.ai works in conjunction with APR implementation tools like Fusion Compiler and provides all necessary capabilities to permute various tool options, design constraints, design specific optimization strategy/recipe variations and learn from each APR run to predict and optimize the settings for achieving target PPA goals. With targeted use-model of DSO.ai based PPA optimization, we demonstrated better PPA on top of best engineer optimized convergence recipe on few critical designs in our SOC. In this presentation, we discuss our case study of scaling up the PPA optimization use model to multiple designs adding up to more than half of the SOC and demonstrating larger PPA benefit at full SOC level. We also discuss new features and use models with DSO.ai to help with scalability for PPA optimization across multiple designs.

PrimeTime Path reporting and ECO efficiency improvement using Machine Learning PBA

Tusharkant Mishra, Associate Technical Director, Samsung India

PBA path reporting is an integral part of STA analysis. Exhaustive PBA runtime can be long, particularly in the pre-signoff phase where the design has many violations. PBA path mode is not sign-off safe and can mask violations. During initial ECO iterations of the design cycle, a high fix rate is desirable for timing violations and also there are good opportunities for power recovery. Exhaustive PBA based timing/power ECO ensures most accurate fixing and avoids GBA mode over-fixing, however it is highly runtime intensive due to the high number of violating paths in the initial iterations.
User requirements to improve on existing flows and solutions were - a simple User Interface, minimal runtime penalty even with many violations and an option to trade QoR for runtime improvements in earlier cycles of ECO and STA reporting.
PrimeTime Machine Learning PBA improves PBA runtimes across the design with a single PBA setting. It is sign-off safe by construction and trades-off runtime vs. accuracy automatically as TNS reduces. In this paper, we will talk about how PrimeTime ML-PBA improves overall Turn Around Time of STA runs and ECO cycles while preserving the benefits of Exhaustive PBA.

SCAN Test Through Functional High-speed Interfaces

Michael Braun, Product Marketing for Semiconductor Test, Advantest

Overall design size and complexity combined with modern ATPG fault models leads to ever-increasing SCAN test data volumes on ATE. Test pattern run times grew from seconds to minutes per device, and conventional scan test access paths are part of the problem: A low-speed, GPIO-based parallel interface may not be sufficient anymore to transfer massive amounts of test data in a reasonable amount of time. In addition, SCAN test patterns are being deployed in System-Level Test (SLT) or even for regular ‘health checks’ of the device in the end application. To enable this, a standard interface like USB or PCIe must be used to transfer the test content, since the parallel test port used on ATE is typically not accessible. This paper presents how to enable SCAN test through functional HSIO on V93000 production ATE: A new type of digital instrument stores all the test data and connects to the device through a standard HSIO I/F using its native protocol. Synopsys High-Speed Access & Test (HSAT) IP inside the device drives the test data through the scan chains. Result evaluation and post-processing is done on the ATE instrument, supported by a TestMAX ALE embedded software component running locally on the tester. Using this new methodology enables a significant increase in the test content transfer rate on production ATE, using widely available and standardized high-speed interfaces with a relatively low pin count. This also enables the transfer of test content between different test insertions, like ATE and SLT, as well as the deployment of production test patterns for in-system test usage.

In-Chip Path Margin Analysis for HPC Adaptive Voltage Schemes and Power Optimization

Steve Crosher, Synopsys

Advanced node technologies underpin the capabilities offered by High Performance Computing. Challenges associated with the physical management of multi-core architectures within high gate density, large scale designs are well documented. Chip power consumption does not only require management but also requires optimizing in order to deploy competitive products and meet user experience expectations. The reduction of voltage supply throughout a chip is attractive, with any reduction saving dynamic power proportional to the square of the supply voltage with further potential static power savings due to lower die temperatures. The question is therefore, by how much can I reduce supply voltages whilst maintaining sufficient functionality and performance of embedded logic during operational mode? 
The set-up and hold timing margins, or ‘slack’, of digital logic is sensitive to supply. Therefore, an opportunity is created to apply timing path monitors at multiple locations within a chip that support adaptive voltage scaling schemes for power optimization tailored to each individual device. Such monitoring should have a small area footprint and be non-intrusive, running in parallel to the functional mode of the device. In this session an overview will be provided of the current requirements of the chip design community, path margin monitor implementation and how such monitors sit within the wider scope of analytics applied to silicon lifecycle management.
