How to interpret (monte carlo simulation)?

pitter
Hi,

Monte Carlo simulation is unseccessful because of an error:

0 t nil ("*Error* ilGetInt: arg must be fixnum" nil))

I found a solution on the internet :

------------------------------------------------
Trap: Autoplot fails, even if sim completes normally

Don't you just love these error messages:

Monte Carlo Simulation completed successfully...

*Error* request.il asiiFinish: error in finish function ("ilGetInt"

0 t nil ("*Error* ilGetInt: arg must be fixnum" nil))

Simulation appears to be hung!!!

Solution: Problem was in the specification of Swept Parameter on the main form. Items in the list of values should be separated by spaces not commas. Click 'Simulation - Stop' to recover.

----------------------------------------------

How shall I interpret it. Where can I find "Swept Parameter on the main form", which main form?

Kind Regards,

 pitter

  • Assuming it's IC5X you're using (it really helps if you can say which version you're using, because the UI is quite different from IC61X), then it's on the Tools->Monte Carlo form. You have the ability to vary a parameter on this form - e.g. temperature by specifying a list of values. The issue was that you needed to space separate these values rather than comma separate them. As far as I can tell, the fix occurred many releases ago, so that's probably not it.

  • Hi,

    It is IC61X version. To run MC simulation I use ADE XL, because there is no such option as 'Tools -> Monte Carlo...' in ADE L window what is actually a different problem.

  • Which IC61 release is it though? (Help->About... in the CIW will give the exact subversion)

    And I'm assuming you're using the "monte carlo sampling" run mode in ADE XL?

    Regards,

    Andrew.

  • I have run into this same issue: At the very beginning of simulation, I get the error \e *Error* ilGetInt: arg must be fixnum - nil. I am using virtuoso version 1c6.1.2.500.5 and attempting to simulate a fairly simple custom circuit.Thanks.

  • Determining a strange error message in a long unsupported of the tools is pretty much impossible (that error is a fairly generic error message, and won't pinpoint the real problem). The version you are using is over 7 years old, and since then we have had IC613, IC614 IC615 and IC616 major releases.

    Please use something more recent that is actually supported!

    Kind Regards,

    Andrew.
