Import spectre netlist

Bernd das Brot
Bernd das Brot over 15 years ago

Hello all,

I have to look for real differences of subcircuits in two spectre netlists. It should be the same circuit, but the names of the nets and instances seemes to be compleetly different. My idea is to cut out the parts of the subcircuits definition, import them to a cell (IC5.141) and use the LVS  (Diva) tool.

Unfortunately, I didn't found any tool to import a spectre netlist. Only for spice netlist or CDL.

Does anybody know how to import a spectre netlist? Or is it possible to feed the netlists to the LVS directly?

 Best regards

     Hello Quek,

     Thank You for For tips.

    You can import the spectre netlist using spice-in (File->Import->Spice) function from IC614.

    Yes, I found this tool here, but in my understanding spice-in is for IC6xx and the OpenAccess database. Does it support the "old" database format of 5.141 ???

    The other alternative is to write a perlscript to convert the spectre netlist to a spice netlist.

    Ohh yeah, I'm wondering what take more time: writing this script (with less knowledge of the both formats) or performing a handmade LVS. .... OK, the netlists have just 91,500 lines, maybe the handmade LVS will take som time, too. :->

    I have a strong feeling to reinvent the wheel, is there nobody, who has written such script ???

    Best regards,

    Bernd
