runams directly on schematic or extracted view

drdanmc

I find it useful sometimes to directly netlist an extracted view.  In the past I've done this with a command line script which launches 'virtuoso -replay netlister.il' to netlist the design.  I though about trying to switch to runams and tried:

runams -lib mylib -cell mycell -view myview -netlist

the problem is it wanted me to give a -state which I don't have.  I tried creating a test bench and a config view and then runams worked but this defeated the whole "quick and dirty" desire.

Do I need to just go back to the -replay file with something like this:

simulator('spectre)

design(libName cellName viewName "r")

createNetlist(?recreateAll t)

    Dan,

    You don't need a state cellView - but you do need a config. You need this whether you're using the UI, runams or OCEAN (with ams as the simulator; you've used spectre there which wouldn't help you). You can just run:

    runams -lib mylib -cell mycell -view myconfig -netlist

    You might need to specify -modelfile if you are using (say) the UNL netlister and need it to be able to run the assembly stage (if there are transistor level circuits in your design being netlisted).

    We have added a new simple way of creating a config from the schematic in an IC617 ISR (it's in ISR6 - might have appeared earlier - I think ISR5). All you have to do is open the schematic and then do Launch->Plugins->Mixed Signal Options->Configuration and then the Configuration->Auto Create Configuration menu will create it and switch you to be using it.

    Regards,

    Andrew.

    ok. For now I'll stick with the replay file. I'd hoped to be able to do stuff like

    runams -lib mylib -cell mycell -view av_extracted

    because I have some tools which work on spectre netlists.

    Thanks

    Dan,

    If you wanted a spectre netlist, runams wouldn't have helped, since it produces Verilog AMS netlist, not a spectre netlist.

    Regards,

    Andrew.
