Forum Post: RE: How to change the transient noise seed for each sample in a Monte Carlo simulation?

There was a conflict that if the netlist contained both mc_auto_noiseseed and noiseseed then the value of noiseseed won and so the mc_auto_noiseseed=yes had no effect. This was fixed fairly recently, in SPECTRE21.1 ISR21 and SPECTRE23.1 ISR1. I'm guessing you're using too old a version of Spectre (this was mid-2023 that it was fixed). Andrew
