Subject: ( DAC 00 #43 ) Correcting How CadMOS' CeltIC Tool Does It's Job
John, nice report.
I wanted to correct a statement made by one of your contributors:
"CadMos sells a tool that sounds a lot like the Moscape tool. It does
static noise analysis. It doesn't look for a switching signal that
slows down another switching signal, instead it looks for a switching
signal that toggles a static signal (which takes a lot more coupling
capacitance)."
The last sentence is incorrect. Our CeltIC tool look at both the impact of
noise on static signals (crosstalk effects on functionality) and the impact
on other switching signals (crosstalk effects on delay). Our CeltIC tool
will generate an incremental SDF that includes both the increase and
decrease in delay for impacted nets. This SDF can be used with static
timing tools such as PrimeTime to calculate the impact of noise on timing.
