Unable to plot from ADE Assembler results tab

unSkilled

IC6.1.8.500-170,

Hi all,

I've been running some simulations using calcVal and I'm unable to plot the output waveforms when I right click select them. The CIW prompts:

"rdbLoadResults("fnxSession1" "./simulation//maestro/results/maestro/MonteCarlo.1/20/dc_over_temp/groupRunDataDir/psf/results/10")
*Error* Results DB handle is invalid."

Using the results browser to navigate there is impracticable since these are MonteCarlo simulations and need to see them all at once. Interestingly, if I use the simulation without calcVal (so the circuit it's uncalibrated) the results load normally.

Any hints?

    First, are you sure you are saving the waveform data for each Monte-Carlo simulation iteration? Please take a glance at the recent forum posting that details how to save the simulation waveform data for each iteration. The default condition for a Monte-Carlo simulation set is not to save the waveform data for each iteration and this will result in an error if one tries to plot the individual waveform results.

    I am not sure of all you simulator and simulation settings, but thought I would initially make this suggestion!

    Hi Shawn,

    Thanks for your reply. Yes, the "save waveform data" was selected and I could actually find the waveforms using the results browser. However, there was another setting that I think was causing the issue. In the assembler plotting/printing options only "plot signals" was selected. I changed it to plot waveform expressions and now I'm able to plot any waveform by right-click --> plot.

    Please contact customer support. I did a quick search and there have been no reports of this error - so I've no idea why it's doing that. You're using the very latest hotfix; whilst it's possible it is something recently introduced, I would have expected somebody to have seen it before.

    This needs investigation as whether the "rdb" is present, is properly formed, and so on - best handled by support.
