After the mega IP acquisitions last year by Cadence (Denali) and Synopsys (Virage) a lot of people are wondering what is next for the commercial Semiconductor IP market. Let me offer my opinion as a person who works closely with foundries and their top customers and the opinion of Dr. Eric Esteve, an expert on interface IP.

The commercial… Read More

Reduced IC leakage at DAC

Reduced IC leakage at DAC
by Daniel Payne on 06-17-2011 at 5:46 pm

Intro
Neal Carney, VP of Marketing at Tela Innovations provided me an update at DAC last week. Their company partnered with TSMC to reduce leakage in IC designs by biasing the gate lengths on your paths that are non-critical to timing.

Notes

Why do this?
– Reduce leakage
– Increase gate lengths on paths with slack
–… Read More


Cadence spinout at DAC

Cadence spinout at DAC
by Daniel Payne on 06-17-2011 at 5:37 pm

Intro
I remember when Celestry was acquired by Cadence because that gave them a hierarchical Fast SPICE simulator to compete with HSIM. In 2007 part of Celestry spun out from Cadence and became Proplus, which now offers a SPICE simulator called NanoDesigner.

Notes
Proplus – US company, founded in 1995 (Used to be Celestry, acquired… Read More


RLCK reduction tool at DAC

RLCK reduction tool at DAC
by Daniel Payne on 06-17-2011 at 5:23 pm

Intro
Most EDA parasitic extraction tools have built-in RC reduction with no user control however at DAC I learned how Edxact offers a stand-along RLCK reduction tool for IC designers that want more control over what happens to their extracted netlists.
