How to plot a graph?

leongec

hello all, i am a newbie for cadence

 I would like to plot a graph on the wavescan. Instead of getting the plot data  from simulation, i need to plot a graph with my own equation. For my understanding, i should load a .raw file into the graph window. My another problem is, how to generate .raw file?

 

Thank you for your advice!

  • The problem is the beginning of the file. If you call the file something.vcvs and make it look like this:

    ;S21
    ;X, Y
    ;Re, Re
    ;freq, S21
    ;Hz, dB
    1.50E+09,-4.15E+00
    1.51E+09,-4.17E+00
    1.51E+09,-4.17E+00
    1.52E+09,-4.10E+00
    1.52E+09,-3.94E+00
    1.53E+09,-3.82E+00
    1.53E+09,-3.79E+00
    1.54E+09,-3.88E+00
    1.54E+09,-4.01E+00

    Then you can directly open it in wavescan or ViVA (IC615) . getAsciiWave  will also read this (the x and y skip values should be 0, because it automatically skips the semi-colon lines).

    The original file you gave can be read with getAsciiWave if you specify ?xskip 4 ?yskip 4.
