Mixed-Signal Methodology Guide

Mixed-Signal Methodology Guide
by Daniel Payne on 08-29-2012 at 11:14 am

Last week I reviewed Chapter 1 in the new book: Mixed-Signal Methodology Guide, and today I finish up my review of Chapters 2 through 11. You can read the entire book chapter by chapter, or just jump directly to the chapters most related to your design role or project needs. With multiple authors I was impressed with the wide range ofRead More


Assertion Synthesis

Assertion Synthesis
by Paul McLellan on 08-28-2012 at 2:46 pm

In June, Atrenta acquired NextOp, the leader in assertion synthesis. So what is it?

Depending on who you ask, verification is a huge fraction, 60-80%, of the cost of an SoC design, so obviously any technology that can reduce the cost of verification has a major impact on the overall cost and schedule of a design. At a high-level, verification… Read More


Power, Signal, Thermal and EMI signoff

Power, Signal, Thermal and EMI signoff
by Paul McLellan on 08-28-2012 at 1:55 pm

Increasingly the challenge with SoCs, especially for mobile, is not getting the performance high enough but doing so in a power-efficient manner. Handheld devices running multiple apps need high-speed processors that consume extremely low levels of power both in operating and standby modes. In the server farm, the limit is … Read More


SpringSoft Laker vs Tanner EDA L-Edit

SpringSoft Laker vs Tanner EDA L-Edit
by Daniel Nenni on 08-26-2012 at 7:00 pm

Daniel Payne recently blogged some of the integration challenges facing Synopsys with their impending acquisition of SpringSoft. On my way back from San Diego last week I stopped by Tanner EDA to discuss an alternative tool flow for users who find themselves concerned about the Laker Custom Layout road map.

Design of the analog… Read More


IP Wanna Go Fast, Core Wanna Not Rollover

IP Wanna Go Fast, Core Wanna Not Rollover
by Don Dingee on 08-23-2012 at 8:15 pm

At a dinner table a couple years ago, someone quietly shared their biggest worry in EDA. Not 2GHz, or quad core. Not 20nm, or 450mm. Not power, or timing closure. Call it The Rollover. It’s turned out to be the right worry.

Best brains spent inordinate hours designing and verifying a big, hairy, heavy breathing processor core to do … Read More


A Brief History of ASIC, part II

A Brief History of ASIC, part II
by Paul McLellan on 08-23-2012 at 8:00 pm

All semiconductor companies were caught up in ASIC in some way or another because of the basic economics. Semiconductor technology allowed medium sized designs to be done, and medium sized designs were pretty much all different. The technology didn’t yet allow whole systems to be put on a single chip. So semiconductor companies… Read More


Book Review: Mixed-Signal Methodology guide

Book Review: Mixed-Signal Methodology guide
by Daniel Payne on 08-23-2012 at 4:00 pm

Almost every SoC has multiple analog blocks so AMS methodology is an important topic to our growing electronics industry. Authored by Jess Chen (Qualcomm), Michael Henrie (Cliosoft), Monte Mar (Boeing) and Mladen Nizic (Cadence), the book is subtitled: Advanced Methodology for AMS IP and SoC Design, Verification and ImplementationRead More


Debugging Subtle Cache Problems

Debugging Subtle Cache Problems
by Paul McLellan on 08-22-2012 at 5:11 pm

When I worked for virtual platform companies, one of the things that I used to tell prospective customers was that virtual prototypes were not some second-rate approach to software and hardware development to be dropped the moment real silicon was available, that in many ways they were better than the real hardware since they had… Read More


Synopsys up to $1.75B

Synopsys up to $1.75B
by Paul McLellan on 08-22-2012 at 4:24 pm

Synopsys announced their results today. With Magma rolled in (but not yet SpringSoft since that hasn’t technically closed) they had revenue of $443M up 15% from $387M last year. This means that they are all but a $1.75B company and a large part of the entire EDA industry (which I think of as being $5B or so, depending on just what… Read More


Cadence at 20nm

Cadence at 20nm
by Paul McLellan on 08-21-2012 at 8:10 pm

Cadence has a new white paper out about the changes in IC design that are coming at 20nm. One thing is very clear: 20nm is not simply “more of the same”. All design, from basic standard cells up to huge SoCs has several new challenges to go along with all the old ones that we had at 45nm and 28nm.

I should emphasize that the paper… Read More
