Deleting PSF data in Simulation

growingmind

Hello,

I am running a simulation using IC6.1.7 Base Version of Cadence Virtuoso/Design Framework. 

I want to run 2 simulations using Transient Noise - one with a baseline transient simulation and then another appended to this baseline, a sweep of three different transient noise seed simulations.

Then I want to operate on those waveforms, basically substract the baseline from the noise simulations and take PSD and so on.  Basically I am following the Cadence Transient Noise Tutorial Note.

Problem is, when I run the two seperate simulations Cadence is deleting the psf data from the previous simulation and it is not available to the calculator to use in analysis.  It says the information is not available when I try to act on it in calculator (even though it is displayed in VIVA still).

I have saved all the plots in ADE - save and plot and even saved everything else in ADE --> Outputs --> Save All.

How can I get ADE to save the previous simulation waveform and then run another simulation with more waveforms and then use them in calculator to do calculations and stop it from deleting previous simulation data ?

Thank you.

  • You didn't say which variety of ADE you're using, so I'll guess at ADE L. The simplest answer is to do Results->Save after each simulation to save the result into a separate directory so that you don't overwrite them each time. If you'd been using ADE XL or ADE Assembler, then normally this would happen automatically as you increment the history on each run, so that's why I'm guessing you're using ADE L.

    Regards,

    Andrew.

    Yes, I am using ADE L.

    So ADE XL automatically creates a new directory for the data in simulation, while ADE L overwrites every time ?

    Yes, although ADE XL (Options->Save) does allow you to control how many history points are kept, or whether you want it to just keep overwriting. ADE L does have some capability to write into new results directory each time (e.g. when using distributed processing), but in general it overwrites the results each time.
