Global Technology Conference 2011

Global Technology Conference 2011
by Paul McLellan on 08-31-2011 at 7:07 pm

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

Layout for analog/mixed-signal nanometer ICs
by Paul McLellan on 08-26-2011 at 5:24 pm

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 catapults Calypto
by Paul McLellan on 08-26-2011 at 10:36 am

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

20nm SoC Design
by Paul McLellan on 08-25-2011 at 12:48 am

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

Formal Verification for Post-silicon Debug
by Paul McLellan on 08-23-2011 at 5:52 pm

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

Silicon One
by Paul McLellan on 08-23-2011 at 5:23 pm

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

HP, Palm, tablets, PCs, smartphones
by Paul McLellan on 08-19-2011 at 2:54 pm

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

Top 5 Reasons for Wasting Power
by Paul McLellan on 08-19-2011 at 2:27 pm

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
by Paul McLellan on 08-19-2011 at 2:12 pm

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

MUSIC in Bangalore
by Paul McLellan on 08-17-2011 at 7:18 pm

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
