Hi yvkrishna,
As what Mike said, ADE-XL runs Monte Carlo simulaton only if the model comply with the basic syntax. I mean the statistic varation is defined in model, including process variation and mismatch variation.
Sometimes ADE-XL runs Monte Carlo with process+mismatch option even if only mismatch variation is defined in the model. It stops with error if neither process nor mismatch is defined in the model.
Please check if there is the key words statistics, process, and [b]mismatch[/] in your spectre model, and where are them? Is there process variation or mismatch variation when you run Monte Carlo process option at typical, fast, and slow corner?
As of what simulation you should run, you need to contact the foundry. Sometimes the foundry thought process+mismatch is too pessimistic, but their model supports process+mismatch.
Best Regards, Yawei
