SemiWiki? There’s an App for that

SemiWiki? There’s an App for that
by Paul McLellan on 09-18-2012 at 7:20 pm

The iPhone version of the SemiWiki App is now available. Download it from the iTunes store, it’s free. The App allows you to look at similar things to the website but much more conveniently adapted to fit the small screen. When you first start up the App you can log in (assuming you are a SemiWiki registered user and why would you… Read More


ARM, Intel, Apple: It’s Mobile Week

ARM, Intel, Apple: It’s Mobile Week
by Paul McLellan on 09-14-2012 at 4:02 pm

As Dan wrote here, we got invited by Intel to IDF and by ARM to a cheeky little party that they organized the day before. I asked ARM if they were announcing anything and they said basically that it would be foolish to make any announcement the week of their biggest competitors big show. Well, that wasn’t a rule that Apple felt like… Read More


Chip-Package-System Webinar

Chip-Package-System Webinar
by Paul McLellan on 09-14-2012 at 2:47 pm

Aveek Sarkar presented a webinar on chip-package-system (CPS) earlier this summer. One of the big challenges with low-power electronic systems is that the performance, power and price goals are mutually conflicting. It’s like the old joke about “pick any 2”. But for a real system all need to be optimized. … Read More


Samsung Invests in Carbon

Samsung Invests in Carbon
by Paul McLellan on 09-12-2012 at 10:00 am

I’ve talked before about how venture capitalists will no longer invest in EDA companies since the prospect for a huge return just isn’t there any more. By big return I mean an acquisition at hundreds of millions of dollars, like SPC, CCR, Ambit, Cadmos, Simplex. But we all know that chips cannot be designed without software… Read More


Hogan University: Second Semester

Hogan University: Second Semester
by Paul McLellan on 09-11-2012 at 7:37 pm

The next event in the Jim Hogan Emerging Companies series (organized by the EDAC Emerging Companies Committee) will be on 17th October at Cadence (I’m guessing in building 5 but I’m sure there will be signs). The specific topic this time will be How to Raise Money and How Not to Spend it. The evening will focus on different… Read More


Verifying Finite State Machines

Verifying Finite State Machines
by Paul McLellan on 09-10-2012 at 2:05 pm

Finite state machines (FSMs) are a very convenient way of describing certain kinds of behavior. But like any other aspect of design, it is important to get everything right. Since finite state machines have been formally studied, there is a lot of knowledge about the types of bugs that a finite state machine might exhibit.

When flipflops… Read More


Have You Ever Heard of the Carrington Event? Will Your Chips Survive Another?

Have You Ever Heard of the Carrington Event? Will Your Chips Survive Another?
by Paul McLellan on 09-06-2012 at 9:07 pm

In one of those odd coincidences, I was having dinner with a friend last week and somehow the Carrington Event came up. Then I read a a piece in EETimesabout whether electrical storms could cause problems in the near future. Even that piece didn’t mention the Carrington Event so I guess George Leopold, the author, hasn’t… Read More


Wiring Harness Design

Wiring Harness Design
by Paul McLellan on 09-04-2012 at 5:18 pm

In 2003 Mentor acquired a company doing wiring harness design. Being a semiconductor guy this wasn’t an area I’d had much to do with. But more than most semiconductor people I expect.

But back when I was an undergraduate, I had worked as a programmer for a subsidiary of Philips called Unicam that made a huge range of spectrometers… Read More


A Brief History of Semiconductors: the Foundry Transition

A Brief History of Semiconductors: the Foundry Transition
by Paul McLellan on 09-04-2012 at 11:30 am

A modern fab can cost as much as $10B dollars. That’s billion with a B. Since it has a lifetime of perhaps 5 years, owning a fab costs around $50 per second and that’s before you buy any silicon or chemicals or design any chips. Obviously anyone owning a fab had better be planning on making and selling a lot of chips if they are going to make… Read More


3D Memories

3D Memories
by Paul McLellan on 09-02-2012 at 4:42 pm

At DesignCon earlier this year, Tim Hollis of Micron gave an interesting presentation on 3D memories. For sure the first applications of true 3D chips are going to be stacks of memory die and memory on logic. The gains from high bandwidth access to the memory and the physically closer distance from memory to processor are huge.

Micron… Read More
