In Cadence Maestro, I want to create a calculator function

Mooh

In Cadence Maestro, I want to create a calculator function. I want the function to plot a vcsv file; it takes the path of the file and plots it as simply as that

    Given that VCSV files can contain more than one signal, you might need more than that (e.g. which column number you want for X and Y). The good news is that there's an existing calculator function that does this - you don't need to create a new one:

    getAsciiWave("jitter.vcsv" 1 2 ?xskip 0 ?yskip 0 ?formatFloat nil ?xName "time" ?xUnits "s" ?yName "V" ?yUnits "V" )

    It already ignores the comment columns at the top.

    That worked perfectly, thank you so much! One more question: do we have a similar function for S-parameters? Ideally, it would take the S-parameter file path and information, then plot S11 or S21 as an example otherwise I need to run a sp simulation with nport cell .

    getData("s1,1" ?result "nrc_pkg_24port" ?resultsDir "/path/to/nrc_pkg_24port.s24p")

    The ?result would be the prefix for the file name, and the first argument is of the form "sN,M".
