Circuit Simulation and Ultra low-power IC Design at Toumaz

Circuit Simulation and Ultra low-power IC Design at Toumaz
by Daniel Payne on 10-06-2011 at 4:31 pm

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 Cell Characterization with a Fast 3D Field Solver

Memory Cell Characterization with a Fast 3D Field Solver
by Daniel Payne on 09-29-2011 at 12:07 pm

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


Analog IP Design at Moortec

Analog IP Design at Moortec
by Daniel Payne on 09-28-2011 at 12:34 pm

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


A Verilog Simulator Comparison

A Verilog Simulator Comparison
by Daniel Payne on 09-22-2011 at 2:40 pm

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, Optimization and Porting

AMS Design, Optimization and Porting
by Daniel Payne on 09-19-2011 at 2:35 pm

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
  • Read More

    by Daniel Payne on 09-13-2011 at 11:21 am

    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


    Another Up Year in a Down Economy for Tanner EDA

    Another Up Year in a Down Economy for Tanner EDA
    by Daniel Payne on 09-13-2011 at 11:00 am

    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

    Manufacturing Analysis and Scoring (MAS): GLOBALFOUNDRIES and Mentor Graphics
    by Daniel Payne on 09-05-2011 at 3:37 pm

    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


    Transistor Level IC Design?

    Transistor Level IC Design?
    by Daniel Payne on 08-26-2011 at 1:23 pm

    If you are doing transistor-level IC design then you’ve probably come up against questions like:

    • What Changed in this schematic sheet?
    • How did my IC layout change since last week?

    In the old days we would hold up the old and new versions of the schematics or IC layout and try to eye-ball what had changed. Now we have an automated… Read More
