Hierarchy is nearly universally used in the SoC design process to help manage complexity. Dealing with flat logical or physical designs proved unworkable decades ago. However, there were a few places in the flow where flat tools continued to be used. Mentor lead the pack in the years around 1999 in helping the industry move from … Read More

How Good is Your Testbench?
I’ve always been intrigued by Synopsys’ Certitude technology. It’s a novel approach to the eternal problem of how to get better coverage in verification. For a design of any reasonable complexity, the state-space you would have to cover to exhaustively consider all possible behaviors is vastly larger than you could ever possibly… Read More
Formal and High-Level Synthesis
Formal verification has made significant inroads in RTL and gate-level verification because it provides complementary strengths to conventional dynamic verification methods; using both provides higher levels of coverage and confidence in the correctness of an implementation. I haven’t heard as much about formal use in … Read More
Innovation in Verification – January 2020
I’m kicking off a blog series which should appeal to many of us in functional verification. Paul Cunningham (GM of the Verification Group at Cadence), Jim Hogan (angel investor and board member extraordinaire) and I (sometime blogger) like to noodle from time to time on papers and other verification articles which inspire us.… Read More
Saving Time in Physical Verification by Reusing Metadata
Physical verification is an important and necessary step in the process to tapeout an IC design, and the foundries define sign-off qualification steps for:
- Physical validation
- Circuit validation
- Reliability verification
This sounds quite reasonable until you actually go through the steps only to discover that some of the … Read More
PAVE360 is Fully Armed!
Siemens today announced a partnership with Arm to “accelerate the future of mobility by redefining design capabilities for complex electronic systems”. I spent time with David Fritz to understand what this really means. You may remember David from our webinar PAVE360: Of SoCs, Digital Twins, and Validating Autonomous Vehicle… Read More
Photonics Come into Focus: 2020 Predictions
In the past, I’ve focused my annual predictions on electronics – ICs and EDA – but recently I’ve turned my focus to photonics, so my 2020 predictions are primarily in this area.
Historically, photonics has been the Gallium Arsenide of technologies; it was, is and always will be the technology of the future. Analysts have forever … Read More
ANSYS, TSMC Document Thermal Reliability Guidelines
Advanced IC technologies, 5nm and 7nm FinFET design and stacked packaging, are enabling massive levels of integration of super-fast circuits. These in turn enable much of the exciting new technology we hear so much about: mobile gaming and ultra-high definition mobile video through enhanced mobile broadband in 5G, which requires… Read More
Computing with Light
I recently wrote about this year’s Cadence Photonics Summit. As I mentioned in that post, it was a fascinating event with several companies providing useful and informative presentations. You can access some of the presentations on the event site. One presentation, given by Jose Capmany of iPronics, was especially interesting… Read More
Avoiding Fines for Semiconductor IP Leakage
In my semiconductor and EDA travels I’ve enjoyed visiting engineers across the USA, Canada, Europe, Japan, Taiwan and South Korea. I’ll never forget on one trip to South Korea where I was visiting a semiconductor company and upon reaching the lobby a security officer asked me to take out my laptop computer, because he wanted me to… Read More
