Using ocnxlRun in a loop

webbyguy

I am trying to run multiple ADE XL runs from an ocean script, but each time I run simulations using the ocnxlRun command the script waits until that job is finished.  Is there any way to setup the ocnxljob such that it doesn't wait on previous runs to finish before starting the next jobs?

 

Thanks

    Hi John,

    OK, fair enough. For the second we have a capability called "pre run scripts" which is in IC615 (it's in IC614 under an engineering release flag) which allows you to effectively run a bit of OCEAN before each iteration of the monte carlo. In fact you can run the monte carlo iteration, run a number of simulations (e.g. to "tune" the design), and then finally do you're measurements. This is supported in ADE XL, and also would work from OCEAN XL.

    For the first, there's no good solution, except you can still use the monteExpr/monteCarlo/monteRun approach - this is still supported for legacy reasons.

    What I would suggest is giving all this info in the service request you're filing, as it gives good justification as to why we should implement ocnxlRun sooner rather than later.

    Note you could do it by using (say) ipcBeginProcess() to launch a background virtuoso (or ocean) session which is loading  an OCEAN script, and that could run at the same time as the second run. But it's less convenient than being able to do a non-blocking run().

    If you run from ADE XL itself, you can do this (submit both jobs simultaneously, without blocking), if you don't mind the UI being open.

    Regards,

    Andrew.
