Hi David, Hmm, that is odd, as -restore is pretty similar to just doing a load() after starting. That compares with replay, which is effectively feeding each line in the file to the main event loop. I...

RE: Virtuoso, monte carlo simulation to measure fervency of ring oscillator
Hi Andrew I need to make PUF (Physical Uncolnable Function ) and test it using monte carlo analysis so, i need to measure the frequency of ring oscillator vs the temperature variations . Many thanks
