hspiceD flat netlisting using -replay

John Barth

Looking to generate a flat hspiceD or spectre netlist to feed some netlist checking scripts. Flat netlists are much easier to post process with simple scripts.  Netlist size not an issue.

Currently using ocn replay from this forum:

envSetVal("asimenv.startup" "projectDir" 'string "testnetlist_dir")
simulator('hspiceD)
design("test" "D2L_X_COUPLE" "schematic")
createNetlist()

What can I add to get a flat netlist instead of hierarchical ?

I did try to export flat cdl from ciw, but that netlister renames all the nets and instances.

Can't seem to get si to create hspiceD in batch mode either.

Thanks for any guidance you can provide

    There is no support in the hspiceD netlister for producing a flat netlist, since one would never be needed for simulation.

    It's not really surprising that the flat CDL netlister renames nets and instances - that's somewhat inevitable since you have to represent the flattened hierarchy somehow...

    I believe the CDL netlister is the only built-in netlister that supports flat netlisting.

    Regards,

    Andrew.
