LVS on mixed signal circuits

hon cheong

Hi,

If I would like to run LVS on a circuit that compose of both analog circuits (handcrafted) as well as digital circuits ( layout generated by Encounter), how can I do that ? while I have schematic for my analog circuits, I do not have schematic for my digital circuits ( I have VHDL code, structural verilog files generated by design compiler, as well as layout generated by Encounter).

Please advice.

Thank You.
Regards,
Hon Cheong

    Hi Hon Cheong

    Currently it looks like you are doing mixed signal lvs as follows:
    a. Import all cdl files as schematic
    b. Import all verilog files as schematic
    c. Do lvs on imported schematics and layout

    You can also do it as follows without importing cdl and verilog:
    a. Use v2lvs to convert verilog netlist to cdl format
    b. Compare with layout using toplevel cdl netlist and the converted cdl files

    Best regards
