Replacing the British Museum Algorithm

Replacing the British Museum Algorithm
by Paul McLellan on 09-14-2015 at 7:00 am

In principle, one way to address variation is to do simulations at lots of PVT corners. In practice, most of this simulation is wasted since it adds no new information, and even so, important corners will get missed. This is what Sifuei Ku of Microsemi calls the British Museum Algorithm. You walk everywhere. And if you don’t walk to… Read More


eSilicon Truly Puts the ‘e’ in Silicon

eSilicon Truly Puts the ‘e’ in Silicon
by Paul McLellan on 09-12-2015 at 7:00 am

eSilicon have a new website. Companies update their websites regularly, so why is this news? Well, eSilicon increasingly does their business on the web. They are not like Facebook, say, where their business is entirely web-based, there is a physical business behind them. So they are more like Lyft for chips. Obviously Lyft requires… Read More


Xilinx is a Software Company

Xilinx is a Software Company
by Paul McLellan on 09-10-2015 at 7:00 am

If you think of Xilinx the word that immediately comes to mind is FPGA. After all they were one of the pioneers of the space. FPGAs are a means of implementing hardware, and the main implementation methodology is RTL-based. This compares to writing software and compiling it for a microprocessor, which is the main software implementation… Read More

Apple: Watch, iPad, tv, iPhone
by Paul McLellan on 09-09-2015 at 3:35 pm

If you didn’t watch the Apple event from the Bill Graham Civic Auditorium this morning, you didn’t miss a whole lot. The only truly different thing announced was the new remote control for the new Apple TV. Everything else was pretty much what you might expect (bigger screen, faster). The whole show seemed remarkably… Read More


Explore Your Interconnect the ICScape Way

Explore Your Interconnect the ICScape Way
by Paul McLellan on 09-09-2015 at 7:00 am

One of the surprises at DAC for ICScape was to be listed on Gary Smith’s list of companies to see. Surprised, since ICScape had never presented their products to him. They were listed under design debug. They don’t have a single product that really falls under that description, but rather a family of tools under the ICExplorer… Read More

"Night Gathers, and Now My Watch Begins"
by Paul McLellan on 09-08-2015 at 7:00 am

What is going on in the watch world? And I don’t mean Game of Thrones‘ nights watch.

Lots, actually. Whether it will amount to a lot remains to be seen. I still think the usefulness versus the price isn’t there yet. Apple has sold 3.5M iWatches (or something close) which for anyone else would count as a runaway success… Read More

SEMATECH, Silvaco and SRAM
by Paul McLellan on 09-04-2015 at 7:00 am

SEMATECH has been around for over 20 years, starting in Austin. Today it is in upstate New York which increasingly seems to be the area for semiconductor research with IBM (still doing research although they sold their semiconductor business to GlobalFoundries), GlobalFoundries’ own Fab 8, the College of Nanoscale Science… Read More


Business Models: EDA Is Software But It Used To Be Sold As Hardware

Business Models: EDA Is Software But It Used To Be Sold As Hardware
by Paul McLellan on 09-03-2015 at 7:00 am

Business models are really important. Just ask any internet startup company that has lots of eyeballs and is trying to work out how to monetize them. It is a lot easier to get people to use something for free, much harder to get people to pay for something especially when they don’t value it much. Different companies that look… Read More


Threat Detection: How To Keep the Crown Jewels Secure

Threat Detection: How To Keep the Crown Jewels Secure
by Paul McLellan on 09-02-2015 at 7:00 am

Let’s just take it as a given that securing IP design data is critical. It’s rather like saying that it’s a good idea to have security in the Tower of London to stop the crown jewels being stolen. IP blocks are the crown jewels of an SoC company.

Data now must be secured within the collaborative teams that share that… Read More


Solido Wrote the Book on Variation

Solido Wrote the Book on Variation
by Paul McLellan on 09-01-2015 at 7:00 am

When I studied mathematical analysis, one of the things that we had to prove turns out to be surprisingly difficult. If you have a continuous function and at one point it is below a line (say zero) and at another point it is above zero, then there must be a point at which the value is exactly zero. In effect, a continuous function can’t… Read More
