There are a few dozen causes of semiconductor failure. Most can be lumped into one of three categories: material defects, process or workmanship issues, or environmental or operational overstress. Even when all those causes are carefully mitigated, one factor is limiting reliability more as geometries shrink – and it… Read More

An Update on the OpenPDK for IC Design
IC designers use EDA tools to implement their logical and physical design, and these tools require foundry-specific information for:
- Design Rule Checking (DRC)
- Layout Versus Schematic (LVS)
- Library Symbols
- Parasitic EXtraction (PEX)
Mastering the Magic of Multi-Patterning
I’ve been quite impressed that modern ICs use a lithography process with 193nm light sources to resolve final feature sizes at 20nm and smaller dimensions. We’ve been blogging about Double Patterning Technology (DPT) some 45 times in the past few years that enable 20nm fabrication, so one big question for me is, “How… Read More
Capturing Analog Design Intent with Verification
Analog IC designers are gradually adopting what digital IC designers have been doing for years, metric driven verification. When you talk with analog designers about their methodology and approach, you hear terms like artisan being used which implies mostly a manually-oriented methodology. Thanks to automation from EDA companies,… Read More
Bringing EDA to India
Why do all three big EDA companies have user group meetings in India? The answer is to grow the EDA market in India because so many multi-national companies have engineers in India doing SoC, and IP design work. In my 35 years of IC design and EDA experience I’ve had the pleasure of working with and knowing many engineers and managers… Read More
Social Media at Mentor Graphics
You can often tell how important blogging and social media is to an EDA company by how much effort it takes to find their blog from the Home page. For the folks at Mentor Graphics I’d say that blogging is quite important, because it shows up as a top-level menu item. Notice also how important Twitter is, their latest tweets show… Read More
Assertions verifying blocks to systems at Broadcom
Speaking from experience, it is very difficult to get an OEM customer to talk about how they actually use standards and vendor products. A new white paper co-authored by Broadcom lends insight into how a variety of technologies combine in a flow from IP block simulation verification with assertions to complete SoC emulation with… Read More
A Hybrid Test Approach – Combining ATPG and BIST
In the world of IC testability we tend to look at various approaches as independent means to an end, namely high test coverage with the minimum amount of test time, minimum area impact, minimum timing impact, and acceptable power use. Automatic Test Pattern Generation (ATPG) is a software-based approach that can be applied to any… Read More
Scan the horizon, P1687 takes us higher
The tech standards cycle almost always goes like this: Problems or limits develop with the existing way of doing things. Innovators attempt to engineer solutions, usually many of them. Chaos ensues when customers figure out nothing new works with anything else. Competitors sit down and agree on a specification where things work… Read More
AMS IC Design at SilabTech
Through my contacts at SemiWiki I was introduced to a mixed signal IP company named SilabTech, and then decided to interview the founder and CEO, Sujoy Chakravarty.
