maximum run numbers for MC sim

sjwprc

Hi, in order to check startup condition, i need to run MC runs as many as possible. It seems there is a limit: 10k runs for one corner in Cadence. 

E.g., even i set 100k runs in MC setting window, The on-going history Status shows : running X/10k complete. 

Thanks.

    You didn't say which version you're using, or whether it's ADE XL, Explorer or Assembler, but as far as I know, ADE runs in chunks of 10000 simulations - so when the first 10,000 are completed, it runs another set. This is related to managing performance and capacity.

    In general there are more efficient ways of running very large numbers of runs (such as using yield verification approaches with sample re-ordering, or high-sigma techniques) which avoid you actually having to run so many points. I can't really point you at the right approach though without knowing which tool you're using.

    Andrew.

    Hi Andrew, thanks for your feedback. Im using ADEXL to run MC sim. Can you share more info about "yield verification approaches with sample re-ordering, or high-sigma techniques".
