What to do with probes

  1. Hi,

    I am reading a bit in the skdfref.pdf and wonder what to do with probes.
    I know probes from Pspice, and they control which signals get plotted.
    Doesn't look like that in Virtuoso. What are the typical uses of a
    probe?

  2. Probe is a way of highlighting things.

    I had a few thoughts about this. It probably possible to make a symbol
    that will have the same effect as the analog artist "add signal to
    outputs". However, the probes in pspice keep working when a change
    occurs in the instance names that make up the hierarchy path to the
    probe. That is the difficult bit with analog artist: even though ADE and
    the schematic editor can communicate, there is no ready made support
    for this. You would need to callback ADE after any instance name change
    in a schematic, so that the running ADE sessions will check wether they
    have this instance in the outputs. Thinks get worse if you want to
    update not only signal outputs but also expressions. And things get
    hairy if you want to also update artist states (you can also wonder
    wether you really want to always do that, w.r.t. to version control.).

    I don t want to paint it black though: if you want the functionality
    to work only on toplevel or top-1 (testbench) that must be doable.

    I once opened a SR for this, and it was void'ed. Wishing you better luck.
