Finding devices with DC currents greater than some threshold

aakhavan

I need to search a large schematic hierarchy for unwanted leakage currents in a DC sim. My current implementation traverses the schematic hierarchy and uses OP() to check the current through devices whose cell/library name match some predefined regex list. Unfortunately, this is extremely slow and causes the whole environment to hang until its done. Is there a better way to do this? Particularly, is there a way to dump all of the dcOpInfo (or a subset, or specific parameters) to an ASCII file and parse that externally?

  • If you're using a recent-ish subversion of IC616, the Outputs->Save All menu in ADE has the ability to add new "info" analyses so that you could save the operating point to an ASCII file in addition to the normal PSF database.

    Here you can see I've added a new row. This file would get saved into the "netlist" directory by default (I think...)

    Alternatively, if using an older version, you could create a file, myinfo.scs with:

    myOpPoint info what=oppoint where=file file="opPoint.txt"

    and then reference this file via Setup->Model Libraries or Setup->Simulation Files and add it as a "definition file".

    Regards,

    Andrew.
