I went to the second Global Technology Conference yesterday. It started with a keynote by Ajit Manocha who is the CEO of about 2 months. I hadn’t realized until someone asked him during the press lunch that he is technically only the “acting” CEO. Actually, given his experience he might be the right person anyway,… Read More

Layout for analog/mixed-signal nanometer ICs
Analog has always been difficult, a bit of a black art persuading a digital process to create well-behaved analog circuits, capacitors, resistors and all the rest. In the distant past, we would solve this by putting the analog on a separate chip, often in a non-leading-edge process. But modern SoCs integrate large amounts of digital… Read More
Mentor catapults Calypto
Mentor has transferred its Catapult (high level synthesis) product line, including the people, to Calypto. Terms were not disclosed but apparently it is a non-cash deal. Calypto gets the product line. Mentor gets a big chunk of ownership of Calypto. So maybe the right way to look at this is as a partial acquisition of Calypto.
It … Read More
20nm SoC Design
There are a large number of challenges at 20nm that didn’t exist at 45nm or even 32nm.
The biggest issues are in the lithography area. Until now it has been possible to make a reticle using advanced reticle enhacement technology (RET) decoration and have it print. Amazing when you think that at 45nm we are making 45nm features… Read More
Formal Verification for Post-silicon Debug
OK, let’s face it, when you think of post-silicon debug then formal verification is not the first thing that springs to mind. But once a design has been manufactured, debugging can be very expensive. As then-CEO of MIPS John Bourgoin said at DesignCon 2006, “Finding bugs in model testing is the least expensive and most desired… Read More
Silicon One
I have talked quite a bit over the last few years about how the trend towards small consumer devices with very fast ramp times. For example, pretty much any time Apple introduces a new product line (iPod, iPhone, iPad…) it becomes the fastest growing market in history. This has major implications for semiconductor design … Read More
HP, Palm, tablets, PCs, smartphones
Hewlett-Packard purchased Palm last year for over a billion dollars primarily to get their hands on the WebOS operating system for powering its tablets and smartphones. It’s turned out to be much too little too late. Despite WebOS being a new operating system with many attractive features, HP’s tablet offering, … Read More
Top 5 Reasons for Wasting Power
Traditionally, David Letterman style, we should really have the top 10 reasons for wasting power in semiconductor design, but here are the five big ones.
Starting with reason #5: Lack of a power gating strategy
Leakage power is a huge proportion of total power and the only way to save leakage power (apart from low leakage cells when… Read More
Design Constraints
Design constraints, which express higher level design intent, are one of the pieces of ancillary data that are critical to the success or failure of a custom (in fact any) design. Design constraints aren’t usually contained within layout files or library information, but without these critical data, designs may not meet specifications.… Read More
MUSIC in Bangalore
When you think of Indian music you might think of ragas for the sitar. But when you think of Indian MUSIC, that is the Magma user group meeting (Magma Users Summit for Integrated Circuits) coming up on September 7th in Bangalore (note: the date has changed from when it was originally announced). It is at Vivanta by Taj on M G Road.
There… Read More
