VerilogA into Device Netlist
Jul 29th, 2010, 1:49am
 
Hello.
Quick query. I have an extracted net list of a semiconductor pn junction device, i.e. the net list of the extracted capacitances, bulk resistances etc. The device is DRC and LVS clean but does not include the devices behaviour.
I have a separate VerilogA electrical behavioural model of the device which takes in a generic trigger pulse and gives the correct (verified) behaviour at its anode and cathode.
Of course If I put both into schematic the block will no longer LVS as the VerilogA is essentially not there.
Instead I want to add the VerilogA model into net list, preferably with code to only simulate if in electrical simulation mode rather than LVS or DCR modes.

The VerilogA prototype is:

module GeigerModel(PLUS, MINUS, PULSE)

Thanks very much.

You probably need to tell us what tools you're using.  Some tools generate a different netlist for LVS than for Spice simulation; I think Cadence has some sort of "hierarchy editor" that allows you to substitute behavioral models for various blocks, etc.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
