Hi John,
I would like to comment on Lun Ye's questions about PrimeTime and signal
integrity.
When Aart mentioned PrimeTime with crosstalk analysis capability, he was
talking about PrimeTime-SI. PrimeTime-SI adds signal integrity analysis
capabilities to PrimeTime. The first release of PrimeTime-SI focuses on
support for crosstalk analysis which is caused by coupling capacitance
between neighboring nets in 0.18 um and below. This coupling capacitance
leads to crosstalk and can cause timing failures (such as the speed-up or
slow-down of net delays).
PrimeTime-SI uses static timing techniques along with coupling capacitance
information in the back-annotated parasitics file to compute the speed-up
or slow-down on nets due to crosstalk. PrimeTime-SI is integrated into the
PrimeTime static timing analysis engine, so it offers high capacity and
performance to analyze crosstalk effects at the block or full-chip level.
As Aart stated at Boston SNUG, PrimeTime-SI is currently available to
limited partners in a beta program. The formal release of the product is
being targeted for the first half of 2001. Currently, the focus is on
analyzing timing effects only. In the future, PrimeTime-SI would be
integrated into the Synopsys physical synthesis solution forming the
backbone of a signal integrity solution throughout the flow.
