EDA software for IC and system design became a commercial business in the early 1980s. In those days, 3 companies – Daisy Systems, Mentor Graphics, and Valid Logic Systems – dominated the emerging EDA industry. However, two small startups that emerged in the early 1980s grew rapidly and merged to form Cadence Design Systems in 1988.… Read More

The Need for OASIS in Post-layout IC Databases
OASIS is a hierarchical IC file format used for IC designs that is gradually replacing GDS II throughout the mask data stages. The compelling reason for using OASIS has always been the reduction of file size, and speed up of processing times through the use of hierarchy and fewer translation steps.
At the 45nm node an actual M1 layer… Read More
Mixed-Signal Methodology Guide
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 of… Read More

Assertion Synthesis
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
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
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.

IP Wanna Go Fast, Core Wanna Not Rollover
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
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
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 Implementation… Read More
