How to export spice netlist?

DaveZhang over 4 years ago

Hi all,

Is there have any command that can export a spice format netlist in Linux shell or CIW?

Any help is appreciated!

thanks.

If you need SPICE, and you have the license to allow access to the hspiceD interface in ADE, you would simply use these SKILL functions in the CIW:

simulator('hspiceD)
design(libName cellName viewName "r")
createNetlist(?display nil)

There's also the CDL netlist format which is SPICE-like. For that, create an si.env file similar to what you get from FIle->Export->CDL and then from UNIX you can use "si -batch -command netlist".

Andrew.

Hi Andrew,

thank you for your reply.

'''createNetlist' works fine, but the netlist exported by this command only shows the information for the top cell view. can we exoprt a hierarchical SPICE format netlist like the CDL format netlist?

It absolutely should be a hierarchical netlist - I can't see why that wouldn't be the case unless your switch and stop views are messed up.

It doesn't (by default) include a subckt for the top level block - it just contains the top level components directly. Maybe that's what you meant? You'd need to add:

envOption('setTopLevelAsSubckt t)

before the createNetlist for that. Here's an example of what it produced (the input.ckt file):
