There’s a French EDA company named DOCEA Powerthat is uniquely focused on power analysis at the ESL level and I had a chance to interview Ridha Hamza to get new insight on ESL design challenges and their approach. Ridha started out doing SRAM design at STMicroelectornics in the 1990’s, moved into the emerging field … Read More

Automating PCB Timing Closure, Saving Up to 67%
The benefits of using EDA software is that it can automate a manual process, like PCB timing closure, saving you both time and engineering effort. This point was demonstrated today as Cadenceadded new timing-closure automation to their Allegroproduct family, calling it Allegro TimingVision. On Tuesday I spoke with Hemant Shah… Read More
What I Didn’t Know about Electronic Design Automation
I started using internal EDA tools at Intel beginning in 1978 and have worked in the commercial EDA industry since 1986, so it was a delight to read a chapter about EDA in Nenni and McLellan’s newest book: Fabless – The Transformation of the Semiconductor Industry. Starting in the 1970’s the authors talk about… Read More
A Brief History of Chip Design at Apple Computer
Steve Wozniak in 1976 designed the Apple 1 while working at HP during the daytime, and he used standard parts to keep costs low, like:
- 6502 CPU from MOS Technology
- 8K of DRAM
- TTL logic for driving video and random logic
- PROM to hold the BASIC language and primitive OS
SoC Functional Verification Planning and Management Goes Big
Big SoC designs typically break existing EDA tools and old methodologies, which then give rise to new EDA tools and methodologies out of necessity. Such is the case with the daunting task of verification planning and management where terabytes of data have simply swamped older EDA tools, making them unpleasant and ineffective… Read More
A Methodology for Assertion Reuse in SoC Designs
As your SoC design can contain hundreds of IP blocks, how do you verify that all of the IP blocks will still work together correctly once assembled? Well, you could run lots of functional verification at the full-chip level and hope for the best in terms of code coverage and expected behavior. You could buy an expensive emulator to … Read More
Before SPICE Circuit Simulation Comes TCAD Tools
I’ve run SPICE circuit simulators since the 1970’s and they use transistor models where the device parameters are provided by the foundry. These transistor and interconnect parameters come from an engineer at the foundry who has characterized silicon with actual measurements or by running a TCAD (Technology CAD)… Read More
Speeding Up AMS Verification by Modeling with Real Numbers
My first introduction to modeling an AMS behavior using a language was back in the 1980’s at Silicon Compilers using the Lsim simulator. Around the same time the VHDL and Verilog languages emerged to handle the modeling of both digital and some analog behaviors. The big reason to model analog behavior with a language is for… Read More
Designing an SoC with 16nm FinFET
IC designers contemplating the transition to 16nm FinFET technology for their next SoC need to be informed about design flow and IP changes, so TSMC teamed up with Cadence Design Systems today to present a webinar on that topic. I attended the webinar and will summarize my findings.
Shown below is a 3D layout concept of an ideal FinFET… Read More
Update on AMS Verification at DVcon
Digital verification of SoCs is a well-understood topic and there’s a complete methodology to support it, along with many EDA vendor tools. On the AMS (Analog Mixed-Signal) side of the design world life is not so easy, mostly because there are no clear standards to follow.
To gain some clarity into AMS verification I spoke… Read More
