extracting spice netlists from layouts

hi u say spice extraction in the sense..
I assume that u need to generate spice netlist from ur verilog netlist in hercules

Using nettran command in herculese u can generate spice netlist

>nettran -i <netlist_file> -outType SPICE -outName <spice_file>

Can u elaborate the question in detail...

Hi Shankar,
Thanks a lot for your reply. I want to extract spice netlist with Star-RC and Hercules for analog circuit. The input is the prelayout hspice netlist. I want to run post-layout simulation with the paratisics. Could you tell how to do it?

Best Regards,
Bangtian Jia
