Synopsys Software Integrity: Find All the Bugs

Synopsys Software Integrity: Find All the Bugs
by Paul McLellan on 05-29-2015 at 9:30 am

A couple of days ago Synopsys announced that they were acquiring Quotium’s product Seeker. This is an interactive application security testing (IAST) product. Synopsys are acquiring the product and the R&D team, not the whole of Quotium. The Seeker solution is a pioneering solution for IAST that helps businesses find high-risk… Read More


WarpStor, the Data Tardis: Small on the Outside, Large on the Inside

WarpStor, the Data Tardis: Small on the Outside, Large on the Inside
by Paul McLellan on 05-28-2015 at 7:00 am

There is a data explosion:

  • IBM says that 90% of all data was created in the last 2 years
  • Smartphone processor development requires 100GB of data per engineer
  • Android testing requires 30GB times the number of tests times the number of testers
  • Biotech simulation, game development and more all require enormous amounts of data

FinFET: The Miller’s Tale

FinFET: The Miller’s Tale
by Paul McLellan on 05-27-2015 at 7:00 am

In Chaucer’s Canterbury Tales, the second of the tales told by the pilgrims is The Miller’s Tale. Since this is a family blog, I’ll leave you to research the tale yourself. But FinFETs hide another Miller’s Tale, due to Miller capacitance, sometimes called the Miller effect. This is significant since in FinFET designs Miller capacitance… Read More


Synopsys Earnings Call

Synopsys Earnings Call
by Paul McLellan on 05-27-2015 at 12:00 am

Synopsys had their earnings announcement and call last week. They were good. In Aart’s own words:I’m happy to report that our second quarter results were very strong and solidify our outlook for the full year. We delivered revenue of $557 million, non-GAAP earnings per share of $0.68 and $155 million in operation cash flow.Read More


How Good Is Your Library? Are You Sure?

How Good Is Your Library? Are You Sure?
by Paul McLellan on 05-26-2015 at 7:00 am

 

One task that is not very exciting but is critical is that of library quality assurance. Many design groups have created their own procedures, often having been burned in the past, to ensure that the libraries that they use are good. Failure to do so has resulted in:… Read More


eSilicon Lyfts Its Game

eSilicon Lyfts Its Game
by Paul McLellan on 05-24-2015 at 3:00 am

We have got used to services like Uber and Lyft (at least in cities that are not so anti-consumer as to ban them, I’m looking at you New York. Et vous Paris). But in most of the semiconductor world we are still stuck standing at the side of the road waving our hand helplessly in the hope that the light on that taxi is actually on. Leading… Read More

Flash Automobiles
by Paul McLellan on 05-22-2015 at 7:00 am

Building flash memory for automotive is not straightforward. Just look at the specs you have to meet for grade 1 qualification:

  • 100,000 cycles of endurance (writing new values)
  • 10 years data retention
  • all at 125°C (also needs to work down to -40°C)

GlobalFoundries have been working with Silicon Storage Technology (which is a wholly-owned… Read More


OneSpin Launchpad, the App Store for Formal Verification

OneSpin Launchpad, the App Store for Formal Verification
by Paul McLellan on 05-21-2015 at 7:00 am

Formal verification is qualitatively different from most other verification. A simulation can pass or fail. But while formal verification can prove that the circuit is correct, or incorrect, it can also return “not proven” which means either that the algorithms realized that they were not powerful enough to prove… Read More


High-Voltage Power Design

High-Voltage Power Design
by Paul McLellan on 05-20-2015 at 7:00 am

Most of what is talked about on SemiWiki is silicon design. After all for regular SoCs it is the only game in town. But for high voltage power applications (think automotive for one big market) there are other more esoteric technologies becoming more attractive.

Silicon has been the material of choice for high-voltage power applications… Read More


Ten Things to Do in San Francisco the Way the Locals Do

Ten Things to Do in San Francisco the Way the Locals Do
by Paul McLellan on 05-19-2015 at 7:00 am

DAC is in San Francisco, of course, and perhaps you have a day or two to do explore the city. Guidebooks will tell you to visit most of these places but there are much better ways to see them than they typically recommend. Follow these instructions and pretend you are a local.

1. Ride a Cable Car. But don’t wait in line for 45 minutes at Union… Read More
