DFM closure is a growing issue these days even at the 45nm node, and IC designers at ST-Ericsson have learned that transitioning from dummy fill to SmartFill has saved them time and improved their DFM score.
The SOC
ST-Ericsson designed an SOC for mobile platforms called the U8500 and their foundry choice was a 45nm node at STMicroelectronics… Read More
I read about how Toumaz used the Analog Fast SPICE (AFS) tool from BDA and it sounded interesting so I setup a Skype call with Alan Wong in the UK last month to find out how they design their ultra low-power IC chips.
Interview
Q: Tell me about your IC design background.
A: I’ve been at Toumaz almost 8 years now and before that at Sony… Read More
Memory designers need to predict the timing, current and power of their designs with high accuracy before tape-out to ensure that all the design goals will be met. Extracting the parasitic values from the IC layout and then running circuit simulation is a trusted methodology however the accuracy of the results ultimately depend… Read More
Stephen Crosher started up Moortec in the UK back in 2005 with the help of his former Zarlink co-workers and they set to work offering AMS design services and eventually created their own Analog IP like the temperature sensor shown below:
We spoke by phone last week about his start-up experience and how they approach AMS design.… Read More
Intro
Mentor, Cadence and Synopsys all offer Verilog simulators, however when was the last time that you benchmarked your simulator against a tool from a smaller company?
I just heard from an RTL designer (who wants to remain anonymous) about his experience comparing a Verilog simulator called CVC from Tachyon against ModelSim… Read More
AMS design flows can follow a traditional path or consider trying something new. The traditional path goes along the following steps:
[LIST=1]
Design requirements
Try a transistor-level schematic
Run circuit simulation
Compare the simulated results versus the requirements, re-size the transistors and go back to step 3 or …

From the President: Another Great YearThanks to innovative, cost-effective technology and excellence in customer support, we’ve just ended fiscal year 2011 (on May 31st) with solid growth. Revenue was up 8%, we added 139 new customers, and we’re continuing to reach out to technology partners for MEMS and for the analog and mixed-signal… Read More
Hardware designers use complex EDA tool flows that have collections of underlying binary and text files. Keeping track of the versions of your IC design can be a real issue when your projects use teams of engineers. ClioSoft has been offering HCM (Hardware Configuration Management) tools that work in the most popular flows of: … Read More
Almost every week I read about a slowing world economy, yet in EDA we have some bright spots to talk about, like Tanner EDA finishing its 24th year with an 8% increase in revenue. More details are in the press release from today.
I spoke with Greg Lebsack, President of Tanner EDA on Monday to ask about how they are growing. Greg has been… Read More
Last week GLOBALFOUNDRIES and Mentor Graphics presented at the Tech Design Forum on how they collaborated on a third generation DFM flow. When I reviewed the slides of the presentation it really struck me on how the old thinking in DRC (Design Rule Checking) of Pass/Fail for layout rules had been replaced with a score represented… Read More
