Hierarchical physical design - issues and methodologies
In this paper, we will examine some of the issues and methodologies encountered during the finishing and physical signoff stages, and discuss how some of the risks can be mitigated by forward planning and careful data management based on successful experiences of Synopsys Professional Services design consultants implementing large designs. We will also look at additional methods that can be used to give a high degree of confidence in the integrity and manufacturability of a large hierarchical design.

More Than Data Management
Managing the people, the data and the technology are just as important as meeting the market window given that without these, the entire project wouldn't function. Throw huge data set sizes, different cultures and business management issues into the mix and the challenges are many.

Complex SoC Testing with a Core-Based DFT Strategy
With scaling technology and increasing design sizes, power consumption during test and test data volume have grown dramatically — making it almost impossible to test an entire design once it reaches manufacturing. But, using a core-based test strategy combined with scan compression offers one of the most effective ways to limit both huge data volumes and high power consumption of complex SoC tests.

Applying Constrained-Random Verification to Microprocessors
Constrained-random verification (CRV) offers a highly effective way to deal with the challenges of microprocessor verification. These verification challenges are overwhelming for many reasons: complex instruction sets, multiple pipeline stages, in-order or out-of-order execution strategies, instruction parallelism, fixed- and floating-point scalar/vector operations, and other features that create a seemly never-ending list of corner cases to exercise. The time required to create traditional directed tests has become unreasonable.

Practical Ways To Estimate, Implement, And Verify SoC Decoupling Capacitance
Deep-submicron systems-on-a-chip (SoCs) require a power-grid voltage drop of much less than 10% of VDD. Decoupling capacitors, or decaps, help achieve this goal by minimizing switching noise.

Delivering Simultaneous Silicon and Software
A chip is of little use without its software. The semiconductor industry realizes this and is more interested than ever in delivering both silicon and software at the same time. Texas Instruments has combined a number of strategies to reduce software integration time from around 18 months to just one to two months.

IC Design at Advanced Process Nodes: Add Flex to your Flow
To handle numerous technical challenges associated with advanced process nodes, chip designers must have a design flow that adapts to evolving requirements and design goals. At the same time, design teams must also deal with project-related challenges, such as achieving consistent design development across geographically distributed design teams, ramping up new sites, and correcting issues with third-party-library and IP (intellectual-property) quality.

Practical Power Network Synthesis For Power-Gating Designs
Although methodologies for power network synthesis typically assume that design tools can freely size sleep transistors for power gating, this assumption does not hold up for real-world SoC designs where the sleep transistors are commonly designed as custom switch cells of fixed sizes.

Proper Planning Assures SoC Power Integrity
Unless they're planned out of the design, power integrity issues like excessive rail voltage drop (IR drop) and ground bounce can create timing problems.

A Practical Approach to Measuring IC Design Productivity
If a project goes beyond its predicted schedule, it directly impacts profitability. With this in mind, Synopsys consulting and design services organization evaluated their own physical design processes across a broad spectrum of their customer design projects to better understand how productivity can be measured and improved.

Metrics Measure IC Design Productivity
IC design productivity is often thought of as an elusive term. From a design team's perspective, it is a difficult concept to assess due to the fact that IC design projects are diverse in their input, application areas, and design approaches.

Power Planning for SoCs
Careful power planning is essential for designs targeting advanced semiconductor processes. David Stringfellow and Kevin Knapp, design consultants with Synopsys Professional Services, give guidance on best practice recommendations that can help to ensure power integrity throughout the entire design flow.

Evaluate IP Timing Constraints Before Use in SOC Designs
When combining intellectual property (IP) blocks from various sources, you must have a complete, high-quality set of timing constraints for efficient SoC timing closure and signoff. Otherwise, IP integration problems can cause long delays.

A Practical Methodology Calculates IR Drop Targets for SoCs
The shift to smaller process geometries has led to a dramatic increase in problems due to IR drop. Michael Solka and Jonathan Young, both with Synopsys Professional Services, explain how the right IR drop target should be found before steps are taken to address the problem.

Consistency in Process and Measurement: Tracking Long-Term Design Productivity Gains
For many design managers, measuring design productivity may seem more difficult than improving it. While the ability to deliver increasingly complex chips all but ensures design teams are making strides toward better design productivity, quantifying this improvement can be elusive.

Pilot Design Environment Integrates Flow
At first glance, the Pilot Design Environment from Synopsys Inc. may sound like a resurrected EDA framework from the late 1980s. But Synopsys claims to be taking a fresh approach with this integrated RTL-to-GDSII design system, sold as a customized offering by Synopsys Design Services.

Dual Threshold Voltages and Power-Gating Design Flows offer Good Results
Design-optimization methodologies and flows that use gates with two threshold voltages (VTH) can achieve excellent results for both power and timing with a high degree of automation. This dual-VTH approach has become crucial for VDSM (very-deep-submicron) chips, in which reduced VTH not only improves performance, but also increases static (leakage) power.

Diversifying Design Trends in North America
From 2001-2003, there was a downturn in semiconductor markets worldwide. Many veterans of the semiconductor industry argued – at the time – that the downturn was nothing new, that the semiconductor market has always been cyclical, and it is a function of supply and demand.

Front-End Signal Integrity Methods Save Back-End Repair Time
Taking steps to prevent signal integrity (SI) problems can greatly reduce the number of SI errors that you have to fix after routing. Good prevention methods thus help minimize last-minute timing-closure panic due to SI issues such as crosstalk delay and noise.
