Hi,
I'm trying to figure out how to do the following in cadence wavescan(viva) or through the calculator.
Let’s say I do an ac analysis. The analysis basically sweeps the frequency and whatever it plots is with respect to frequency (frequency is on the x-axis). I want to create an expression which includes, besides other things also the frequency. Let’s say I want to plot a*f+b where “a” and “b” are just some numbers, “f” is the frequency. Note, I want to plot this thing, not calculate it for a given frequency value. I can’t figure out how to get the frequency from the AC analysis and include it in the expression. Since ac plots are generated versus frequency, that frequency vector should be accessible somehow, just thinking logically. Can you suggest a way of doing this? Please, note that I would prefer not to do this with ocean or writing veriloga or skill. May be just using the calculator.
The same question stands for transient analysis and including time as a variable in an expression.
Thanks
