use output signals from other circuits as input for simulation

I have two circuits A and B. I simulated the circuit A and has some waveform results. Can I save those some of the waveform and use it as a input signals to simulate in the circuit B?

    If you run the first simulation, you could plot the output curve that's going to be the input to the next simulation. Then in ViVA, select that trace and do Right Mouse->Send To->Export and pick Files of Type to be "SPECTRE". Give a file name (you can clip and interpolate should you need to, or just save the raw data).

    You can then use a vsource with the type as "pwl" and specify that you want to read the data from a file, and give the file you saved from the first simulation (can also be done with vpwlf from analogLib).

    Regards,

    Andrew.

    Thanks. I did almost the same thing sometime ago but I saved the file type as excel file. Which one is better, excel or spectre file?

    If you're using Spectre, I'd probably use Spectre format...
