A Brief and Personal History of EDA, Part 4: Cadence, Synopsys, and Mentor Graphics – The EDA Era

Rising complexity drove the creation of ever-more-powerful tools for electronic design. When circuit board and IC layouts escaped the bounds of pencil, paper, and manual dexterity, CAD tools from Applicon, Calma, and Computervision appeared. When polygon representations no longer sufficed as the first gate arrays appeared, CAE tools from Daisy, Mentor, and Valid appeared. These CAE companies attempted to provide all-in-one design suites for ICs and circuit … Read More → "A Brief and Personal History of EDA, Part 4: Cadence, Synopsys, and Mentor Graphics – The EDA Era"

Understanding and Optimizing SoC Hardware Performance

Are you involved in developing SoCs? Are you banging your head against the wall, desperately trying to determine why you aren’t obtaining the performance promised by the providers of your processor, interconnect, and DDR memory controller IPs? Do I have good news for you? (Spoiler alert. The answer to the last question is a resounding “Yes!”)

In many ways … Read More → "Understanding and Optimizing SoC Hardware Performance"

AMD Rocks with New Versal Gen 2 AI Edge SoC FPGAs

The awesome new AMD devices to which I’ve just been introduced have sparked a trip down memory lane (I know you’re surprised, because I pride myself on my laser-like focus that prevents me from wandering off into the weeds). I remember the 1970s and early 1980s when we thought the simple programmable logic devices (PLDs) of the time were so cool. Those were heady days … Read More → "AMD Rocks with New Versal Gen 2 AI Edge SoC FPGAs"

A Brief and Personal History of EDA, Part 3: Daisy, Valid, and Mentor Graphics – The CAE Era

By the end of the 1970s, the leading CAD companies, including Calma, Applicon, and Computervision had started to lose interest in the electronics market and turned to mechanical CAD. Quite possibly, this lack of interest reflected the demand by electronics and semiconductor companies for something more than efficient drafting systems. The drawings produced by CAD systems were fully capable of producing photomasks for circuit boards and ICs, … Read More → "A Brief and Personal History of EDA, Part 3: Daisy, Valid, and Mentor Graphics – The CAE Era"

How MediaTek Optimizes SI Design with Cadence Optimality Explorer and Clarity 3D Solver

Sponsored by Cadence Design Systems

In the era of 5G/6G communication, signal integrity (SI) design considerations are important in high-speed interface design. MediaTek’s design process usually relies on human intuition, but with Cadence’s Optimality Intelligent System Explorer and Clarity 3D Solver, they’ve increased design productivity by 75X. The Optimality Explorer’s AI technology not only improves productivity, but also provides helpful insights and answers.

Hi Tom -- thanks for sharing -- I'm hoping to meet up with Ben when I visit the UK this summer to see my dear old mom :-)

Thank you for the compliment, metasequoia. I hope you find the series useful. There are five more articles to go in this EDA history, with a few things that surprised me, and I was there!

Steve, You do an absolutely outstanding job researching and writing your articles! Thank you.

This all sounds good ... if they are making paper weights or boat anchors. They are totally ignoring the fact that electronics must do more than consume power and dissipate heat. Space heaters are much less expensive. There once was a dream of Intel developing some kind of language/tool to ...

Indeed, a funny story. I'd have to ask you to cite references to Calma's being the "most popular IC layout platform" in the 1980s. If you're referring to custom IC layout, especially analog, especially at Datel where you worked (I used Datel parts as a design engineer), then sure. If ...

So, I have a funny story of the time Welch brought the BoD to tour the labs. My team had setup a demo in the Calma room, but because the PR folks thought it would be undignified for them to bend over to see our screens, we propped each one ...

Mike, thanks for writing about your personal experiences. Jack Welch became GE's Chairman and CEO in 1981 and GE's semiconductor businesses seem to have wound down swiftly after that. I've no doubt that it took years to run out Calma's leadership, but I've seen no evidence that Calma was a driving ...

Steve, I'm enjoying your history of the EDA industry, but have a few comments to add regarding Calma. A bit of my personal EDA history: In 1981, I was at the GE Corporate R&D (CR&D) Labs in Schenectady, when Calma became one of the components of the ...

Let's take a vote -- how many of us want to spend our days reading nothing but whitepapers? Would we learn a lot? Yes. Would we enjoy spending out days this way? No. For myself, I like to think that people enjoy my articles in their own right--I think I've ...
