Question regarding running parametric simulations using Ocean

gurusub

 Hi all,

I have a set of design variables in my schematic. I would like to input multiple data vectors to my schematic and save the output data in Ocean

For example, If P is a set of parameters P={p1,p2,p3,p4} (p1-p4 are the design variables in the schematic). I would create a matrix of data values with different instances of P ie my data matrix would look like 

Q=[-------P1---------

     --------P2---------

    ---------P3--------]

and so on where each Pi contain (p1i, p2i,p3i,p4i). (In other words I want to use the analogus of paramset command in Spectre for ocean). I would like to simulate my circuit for these values in Q and make some measurements using Calculator function and finally store the output data in the text file. Can somebody please go through the steps in accomplishing the same?

 

Thanks,

 

Guru

  • I filed CCR number  799087 to get the documentation fixed.

    I just did an awvPlotWaveform(winId list(v("node"))) and it worked fine with family data. If that doesn't work, perhaps you should contact customer support, providing your psf directory so that we can investigate. If you really want to pull it apart, you can do:

    sig=v("node")
    slice1=value(sig 'CAP 1.5p)
    slice2=value(slice1 'VDD 2)

    etc. You can either use the value() function without a parameter name, and then it finds the value against the innermost sweep (which might be time, frequency if it's a tran or ac analysis, or you can give one of the sweepNames.
