why in ADE XL monte carlo simulation, the default number of runs is set as 200 ?

Can anyone explain how the number of runs influence the results?

  • Andrew Beckett

    The default number is completely arbitrary. The number of samples you need rather depends on what you're trying to achieve. It's just controlling the number of samples you have in your experiment; whether that's enough to draw a particular conclusion from the result depends on many things.

    It's hard to answer this in a few words without knowing your understanding of statistics. There's this blog on the subject: https://community.cadence.com/cadence_blogs_8/b/cic/posts/fast-yield-analysis-and-statistical-corners which covers it, but in fact in ADE Explorer and Assembler there's now a simpler task-based flow which uses the Virtuoso Variation Option capabilities to perform fast monte carlo by using methods such as sample reordering to verify yield more quickly.

    Probably best to talk to customer support or your account team about this - hopefully they can get an application engineer to talk to you in more depth.

    Regards,

    Andrew.
