FinFET Design Challenges Exposed!

FinFET Design Challenges Exposed!
by Daniel Nenni on 04-07-2013 at 6:00 pm

The first mention of FinFETs appeared on SemiWiki after the ISSCC conference in 2011. Dr. Jack Sun, TSMC Vice President of R&D and Chief Technology Officer, spoke about the power crisis the semiconductor industry is facing and FinFETs was one of the promising technologies that could help us. Since then, we have posted 100+ … Read More


Laker Analog Prototyping

Laker Analog Prototyping

Over the years many attempts have been made to increase the level of automation in analog design. Most of these have not been especially successful. Probably part of the reason was inadequate technology but also there is an attitude that “real” analog designers design polygons on the bare silicon. I think two things… Read More


Laker Wobegon, where all the layout is above average

Laker Wobegon, where all the layout is above average

TSMC’s technnology symposium seems to be the new time to make product announcements, with ARM and Atrenta yesterday and Springsoft today.

There is a new incarnation of Springsoft’s Laker layout family, Laker[SUP]3[/SUP] (pronounced three, not cubed). The original version ran on its own proprietary database.… Read More


Virtuoso has got you cornered

Things you don’t know about Virtuoso: we’ve got you cornered.

That is the title on a Cadence blog item last week. It is actually about variability and how to create various corners for simulation and analysis, but given Cadence’s franchise for Virtuoso, its lock-in through SKILL-based PDKs and so forth, it … Read More


Blitz, blazing fast layout

Blitz, blazing fast layout
by Paul McLellan on 11-29-2011 at 8:00 am

One of the challenges with today’s SoCs is that chip-finishing, putting the final touches to the SoC working at the chip level, stresses layout editors to the limit. Either they run out of capacity to load the entire chip, or they can handle the entire chip but everything is like wading through molasses, it takes an awfully … Read More


Layout for analog/mixed-signal nanometer ICs

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


OpenAccess

OpenAccess
by Paul McLellan on 06-21-2011 at 1:11 pm

Probably everyone knows that openAccess is a layout database. It was originally developed at Cadence (called Genesis) but has since been transferred to Si2. Strictly speaking, openAccess is actually an API and the database is a reference implementation. The code is licensed under a sort of halfway to open-source: you can use … Read More
