Hi All,

I am using IRUN ans SPECTRE engines for verifying a mixed signal design. I am curious to know what are the methods which people use to achieve faster transient simulation. For eg: I use dynamic parameter option for lteratio. Till some time where accuracy is not important and I need large time steps, I set lteratio to 1e3 and then take it down to <10. I would appreciate if someone can point to a methodology covering aspects on faster AMS verification as accuracy is not so important in most of the AMS simulations.

Thanks

Hi Frank,

Thanks for your suggestion. I am looking more for analog solver related options. Basically how to ensure larger time steps. The accuracy of results is not so important. I usually set lteratio to a large value like 1e3 and change method to euler. But I was wondering if there are other options to play around. I tried using minstep but that doesn't ensure larger time steps.
