CDC Functional Checks taking too much time.

arunvaidya
Hi there,

I am currently engaged in closure of CDC functional checks but to my frustration the run for CDC functional checks is taking a great deal of time and till now its just too slow to see it finish. I would like to know if there is any way on how I may investigate this problem and hopefully speed the runtime considerably. The design has a gate count of around 2.8 million.

FYI: There are no errors received during the run.

  • You mentioned CDC functional checks which apparently means multiple cycle checks as opposed to the first level static checks.

    Functional checks involve resetting flops and proper design set-up before checking. With multiple cycles the potential function can become very compilicated quickly. Especially for a large design like your own.

    I don't know if there is a "one size fits all" type of solution in this case. I think the best way to investigate is to contact Cadence support and talk to them. If you find a solution please share it with us!
