TSMC OIP: Soft Error Rate Analysis

TSMC OIP: Soft Error Rate Analysis
by Paul McLellan on 09-09-2013 at 1:34 pm

Increasingly, end users in some markets are requiring soft error rate (SER) data. This is a measure of how resistant the design (library, chip, system) is to single event effects (SEE). These manifest themselves as SEU (upset), SET (transient), SEL (latch-up), SEFI (functional interrupt).

There are two main sources that cause… Read More


Rapid Yield Optimization at 22nm Through Virtual Fab

Rapid Yield Optimization at 22nm Through Virtual Fab
by Pawan Fangaria on 09-09-2013 at 10:00 am

Remember? During DAC2013 I talked about a new kind of innovation: A Virtual Fabrication Platform, SEMulator3D, developed by COVENTOR. Now, to my pleasant surprise, there is something to report on the proven results from this platform. IBM, in association with COVENTOR, has successfully implemented a 3D Virtual Fabrication… Read More

If you have ever send a Request For Quotation (RFQ) for an ASIC including processor IP core, memories, Interfaces IP like PCIe, SATA or USB and Analog function like Analog to Digital Converter (ADC) or Digital to Analog Converter (DAC), you have discovered, like I did a couple of years ago, that these Analog functions may be the key… Read More


Test Compression and Hierarchy at ITC

Test Compression and Hierarchy at ITC
by Daniel Payne on 09-09-2013 at 8:00 am

The International Test Conference (ITC) is this week in Anaheim and I’ve just learned what’s new at Synopsys with test compression and hierarchy. Last week I spoke with Robert Ruiz and Sandeep Kaushik of Synopsys by phone to get the latest scoop. There are two big product announcements today that cover:… Read More

One of the benefits of blogging is that you put a stake in the ground to look back on and see how how things have changed over the years. You can also keep a win/loss record of your opinions, observations, and experiences. Last year I posted the “SemiWiki Analytics Exposed 2012” blog so here is a follow-up to that.

Xilinx At 28nm: Keeping Power Down

Xilinx At 28nm: Keeping Power Down
by Paul McLellan on 09-08-2013 at 2:26 pm

Almost without exception these days, semiconductor products face strict power and thermal budgets. Of course there are many issues with dynamic power but one big area that has been getting increasingly problematic is static power. For various technical reasons we can no longer reduce the voltage as much as we would like from one… Read More

[This blog embargoed until 10am China time]

An interesting thing happened to me this week. I had two press briefings. No, that wasn’t the interesting thing and if you have sat through a press briefing you will not regard them as recreation. I do it for you, Semiwiki readers. Even though, as this week, the briefings are given … Read More


SpyGlass: Focusing on Test

SpyGlass: Focusing on Test
by Paul McLellan on 09-07-2013 at 5:51 pm

For decades we have used a model of faults in chips that assumes that a given signal is stuck-at-0 or stuck-at-1. And when I say decades, I mean it. The D-algorithm was invented at IBM in 1966, the year after Gordon Moore made a now very famous observation about the number of transistors on an integrated circuit. We know that stuck-at… Read More


Why I dumped my iPhone5 for a Samsung S4!

Why I dumped my iPhone5 for a Samsung S4!
by Daniel Nenni on 09-07-2013 at 5:00 pm

A good friend and dog walking partner was on the smartphone Apple/Android fence last year so I pushed him over to Apple and the result was the infamous “8 Reasons Why I Hate My iPhone5” Blog. After months of complaining I bought him a Samsung S4 and gave his iPhone5 to my very appreciative wife so all is well that ends well, maybe.

Base Stations Move Away From Fixed Architecture DSP

Base Stations Move Away From Fixed Architecture DSP
by Paul McLellan on 09-06-2013 at 1:59 pm

Handsets moved away from fixed architecture DSP some time ago, driven by two main factors. Fixed architecture DSP consumed too much power to get good battery life in the smart-phone era, but the consumer air interface was changing fast: W-CDMA, HSPA, WiMax, 3G, LTE (which is actually a whole ‘spectrum’ of different… Read More
