    How to use frequency in calculator when doing AC Sweep in Virtuoso Reply

    Hi everyone, I'm doing an AC sweep for a circuit and I am interested in performing a calculation that requires I divide each point by the frequency at that point and I do not know the syntax for frequency during an AC sweep. For a transient sim where my frequency variable is set too "freq" I could just do VAR("freq"), but for an ac sweep I do not know what name the program assigns to the frequency variable or how I can reference it. Does anyone know how to do this?

    Basically, if I were computing V/f in an ac sweep, I want to know what the syntax is for the "f" component"

    Take any output from your AC simulation - e.g. VF("/out") - the vf button on the calculator can generate this from some node in your circuit - and then use the calculator xval function. This will generate a waveform with the x-axis values as the y-axis - and so it will give you a waveform of frequency versus frequency.

    You can then use this in any calculation.

    Regards,

    Andrew.
