Infopoints

analogy

Is there a way to define a range of info points for transient simulations ?

    OK, if you're using a recent enough version of spectre, you can get away with save *:oppoint (note, no "s" on the end). However, to be safe, you might want to use:

    save *:oppoint sigtype=dev

    Otherwise the wildcard won't necessarily find the devices (it used to only find nodes). The sigtype=dev doesn't do any harm though in newer versions.

    If you do this, it will save the operating point parameters at every time point into the tran results.. No need to use infotimes. Note that the "Save Final Op Pt" option has nothing to do with this either. All that does is tell spectre to save a single operating point at the very end of the transient (saved in a different result database, the finalTimeOp (or something like that)).

    The infotimes approach will save a complete operating point into a database at each of the time points you specify. It will end up in something like a tran_info database (I'm not doing this from ADE at the moment so I'm not sure what it gets called from ADE off the top of my head). That's separate from the tran results.
