How do you benchmark a processor? It seems like it should be easy, just run some code and see how fast it is. Traditionally processors were indeed benchmarked by raw performance like GMACS, GFLOPS, memory bandwidth and so on. But in today’s world where systems have become very complex and applications very compute intensive, the… Read More

Happy Birthday Dear Cadence…
Cadence is 25 years old this year, on June 1st if you want to be precise.
The most direct ancestor of Cadence was SDA (which might or might not have stood for Solomon Design Automation). SDA was founded by Jim Solomon in 1983. It turns out that a guy I shared an office with while we were both doing our PhDs in Edinburgh Scotland was one of … Read More
An EDA Acquisition that Worked
I first heard about Andrew Yang back in 1993 when he founded a Fast SPICE company called Anagram, then acquired by Avant! in 1996. Andrew’s latest EDA company Apache Design, Inc.was started in 2001, then acquired by ANSYS in 2011. Most EDA mergers simply don’t work because of one or more reasons, like:
- Incompatible
How Resistant to Neutrons Are Your Storage Elements?
There are two ways to see how resistant your designs are to single-event errors (SEE). One is to take the chip or even the entire system and put it in a neutron beam and measure how many problems occur in this extreme environment. While that may be a necessary part of qualification in some very high reliability situations, it is also … Read More
Electronic System Level: Gary Smith
Gary Smith has been talking about how the electronic system level (ESL) is where the future of EDA lies as design teams move up to higher levels encompassing IP blocks, high level synthesis, software development using virtual platforms and so on. At DAC this year in Austin he talked about how the fact that EDA controls the modeling… Read More
RTL Design For Power
My Samsung Galaxy Note II lasts about two days on a single battery charge, which is quite the improvement from the Galaxy Note I with only a one day battery charge. Mobile SoCs are being constrained by battery life limitations, and consumers love longer-laster devices.
There are at least two approaches to Design For Power:
- Gate-level
Robust Design <- Robust Flow <- Robust Tools
I could have written the sequence of the title in reverse order, but no, design is the one which initiates the need of a particular flow and the flow needs support of EDA tools to satisfy that need. It’s okay if the design is small; some manual procedures and workarounds/scripts may be able to perform certain jobs. However, as the design… Read More
When Is a Good Time to Start Using High-Level Synthesis?
Of course if you are in the business of selling high-level synthesis (HLS) tools then the obvious answer is immediately. Start at 9am tomorrow morning. But a more realistic answer is when you are having to do something completely new. If you are working on a legacy design, perhaps with pre-existing IP, then moving the design up to … Read More
What Do Brazil and Sweden Have in Common?
Well, Sweden is not noted for its carnivals, Brazil is not noted for it’s tall blonde blue-eyed women, Sweden’s climate is not great for growing sugar cane and Brazil’s isn’t great for reindeer. Both countries speak languages with odd-sounding vowels but they are not the same language. But, ding, Jasper… Read More
How many consortia does POWER need to succeed?
Sometimes press releases just make me scratch my head. Today’s example comes from IBM: after tying PowerPC and Power.org in knots for almost 20 years with rules and restrictive licensing, IBM breaks ranks and sets up ANOTHER consortium with different players.… Read More
