ADE XL Monte Carlo Simulation: "Error evaluating ocean expression"

lperktold
 Hello All,

 I am experiencing a rather strange behavior of ADE XL when it comes to evaluate the expressions defined in the
'Outputs Setup' section during a monte carlo run.

 The simulation stops (after the first run has finished) with an error like:

 ERROR (SPECTRE-8003): designParamVals: Error evaluating ocean expression `DE_1_I_Bias_6_45=average(IT("/I0/I0/I0/T7/D"))'.

 If I disable all the expressions in the 'Outputs Setup' pane the simulation runs fine. I can then use the 'Re-evaluate Result' button in the 'Results' pane to evaluate my defined expressions without any problems.

 I am using

- Spectre Version 7.1.1.187.isr11 64bit -- 18 Aug 2009
- Virtuoso version IC6.1.4.500.3

 Anybody else, experiencing this kind of strange behavior?

Cheers,
         Lukas

  • Please contact customer support. I recall there being an issue with Monte Carlo in a certain range of spectre versions, so you might want to try running with the latest MMSIM hotfix first (I can't find the details though from a quick search).

    I thought initially it might be an issue with plotting waveform expressions with Monte Carlo, but the expression you have their should be producing a scalar result.

    As a workaround, you might want to try turning off running the "nominal" run from the Monte Carlo options form in ADE XL.

    Regards,

    Andrew.
