Scenarios – Certain and Less So

Feeling somehow less worthy in the shadow of the passing of Bob Pease… (with no offense intended towards Docea…)

I spent a few minutes with Docea at DAC a couple weeks ago. You may recall their Aceplorer product dealing with both power and thermal analysis. Two things caught my eye, one of which is a new feature, the other something they’re working on.

The new feature is scenario generation. This is particularly applicable to multi-mode designs, where different modes are exercised as different scenarios. Marketing might refer to them as high-level use cases. Not only is this intended for what-if analysis and architecture optimization, but the results can also be fed to virtual platforms for downstream evaluation.

The thing they’re working on is 3D IC modeling (who isnt’?). This is actually something they announced last year in association with French research group CEA-Leti. I learned a bit more about what it is they’re paying particular attention to.

While they can see their way clear on power modeling for 3D ICs, they’re tinkering a bit more with the thermal side to see if their approach can work. They don’t use a full solver for thermal analysis; they use thermal RC network models, and extending that to stacked dice and all of the bits and bobs that may end up in the sandwich for thermal or redistribution purposes makes it something less than a chip shot.

More info on their latest announcement (plus now-expired discussion of their DAC demos) in their release

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.

GaN for Humanoid Robots
Sponsored by Mouser Electronics and Infineon
In this episode of Chalk Talk, Eric Persson and Amelia Dalton explore why power is the key driver for efficient and reliable robot movements and how GaN technologies can help motor control solutions be more compact, integrated and efficient. They also investigate the role of field-oriented control in humanoid robotic applications and why the choice of a GaN power transistor can make all the difference in your next humanoid robot project!
