Using Custom SKILL functions with Monte Carlo in ADE and OCEAN

gwong

The workaround (#1) provided below did not work for me.

Here's my error message

     ERROR (APS-8003): subckts: Error evaluating ocean expression `txpp_Q0=dataJitter(clip((VT("/I0/ICORE_Q0CP") -     VT("/I0/ICORE_Q0CN")) 1e-08 1.5e-08) (1 / 1.25e+10) 0)'.

Unsuccessfully evaluated export statements (based on return code).

Analysis `mc1' was terminated prematurely due to an error.

It works if I enter the expression in the CIW window.

I also tried using OCEAN by loading the SKILL routine in the monteCarlo.ocn script.  I get the error message too.

  Thanks in advance for your help.

  • Hi Gary,

    I see this is being dealt with via SR  42066046. I've checked, and the workaround in the solution mentioned above does work - but best followed up via the SR (I've been talking with the AEs dealing with it).

    Loading the code in the monteCarlo.ocn script won't work, because the key thing is that spectre starts an "artil" process to do the calculations, and the artil process needs to have any custom code loaded.

    Andrew.

  • Hi Andrew,

     

    Thanks for responding to my post.  I will work with the AE in resolving the problem.

     It sounds like if I want to run OCEAN, I must use the 2nd workaround stated in the link. 

    Regards,

  • Hi Gary,

    No, because I got your testcase working using the first workaround. Both approaches are perfectly valid. I believe the AE will have contacted  you by now to clarify this.

    In fact that solution was written by me!

    Andrew.

  • Hi Andrew,

     Yes, the AE contacted me and I was able to run it successfully using the gui & OCEAN.  I misinterpreted what was required for OCEAN.

  • Hi Andrew, I was reading the solution, but was enable to understand it !! sorry if you can just clarify for me that point: in the first workaround , you gave a unless statement which loads the required code, between curly brace, so what should we do with this {unless ..} put it in a montecarlo expression like monteExpr("dummy_expression" "{unless(...)}") am i right ?? and in the corpus of the jitter.il we should just put our function ;;::: procedure( jitter() ;;;some code ) many thanks
