AC Sim Output Setup Issues

greywanderer

Hi,

I have the following setup defined in my outputs.

After the simulation, I can see the "AC CL Gain" but nothing is seen for "AC CL Gain at 10kHz".

Both the outputs are shown as plots. Any comments on why this might be happening?

Also, when I include these outputs in the montecarlo simulation, I dont see the "10 KHz value" listed in the variations. I have dc parameters in there that seem to be ok. This may be because the "10 KHz Value" appears as a "plot" and not a "value". Any suggestions on how to get the "value" and not the "plot"?

Thanks much!

    Not sure which version you're using, but in the latest IC6.1.8 ISR (.500.21) I get it shown in the results table as complex(1.799,-550.3u) - for example. I would expect the result to be complex, and maybe it doesn't get plotted or output in the table in the version you're using.

    Almost certainly though you don't want it to show the complex value anyway. The v("/vo" ?result "ac") would give you a complex waveform, and plotting complex waveforms would normally automatically plot as magnitude (you can choose to change that post-plot to be db20 or something like that). Probably you want to do: value(mag(v("/v0" ?result "ac")) 10k) instead - I expect that will solve your problem. If it doesn't, please provide the Virtuoso sub-version you're using (Help->About will tell you this).

    Regards,

    Andrew

    Yes. That fixed both the issues. Thanks much.
