Video Demo: ViVA-XL - Fast Waveform Viewing

Comments(2)Filed under: Custom IC Design, ViVa-XL, Fast Waveform Viewing, MMSIM, SimulatorsIt’s happened to each of us at some point in time. Your long simulation is finally complete and you eagerly load up the crucial results you’ve impatiently been waiting for. Much to your chagrin, your waveform tool grinds to a halt as it chokes on your enormous signals. Designers can completely avoid this spinning hourglass scenario by taking advantage of the fast waveform viewing capabilities in ViVA-XL and our MMSIM simulators. In this demo I cover how to enable fast waveforms, explore the data created, and show off how fast it really is. There are additional details in this sourcelink solution.

Interesting tip! However I'm getting this feeling of cadence being schizophrenic about the database formats. I thought that the sst2 database format was the new generation and recommended format which was far more efficient than the psf format. Is Cadence now recommending that we use the psf format with the fast viewing option turned on?
Is there a place where I can see a comparison of the pros and cons of the different formats and a simple recommendation of what to use under what circumstances?

Hi Jose...First off, sorry for the delay in responding.  RTSF is preferred over SST2 in situations where you have a lot of timepoints.
