ViVA: Post processing CSV file

Nasser Arif

Hi,

We are doing a spice simulation, after settling the voltage value at particular net, we clipped that value between the settled point (say 9u to 10u)

Now, I want to give this as stimuli to other circuit, if i directly give the csv flie (from 1st simulation) we will be wasting simulation time till 9u,

we are looking a way to change the csv file, between 0-1u (subtracting 9u from all time in saved csv), 

Currently we are using XL sheet to do the calculation, but it require lot on manual work.

Thanks,

Nasser

    Hi Nasser,

    Use the lshift function in the calculator:

    lshift(clip(v("/OUTM" ?result "tran") 9u 10u ) 9u )

    Then save that as CSV (assuming I've understood you correctly). The lshift function shifts the x-axis of the waveform left by the specific amount.

    Regards,

    Andrew
