I am using DRACULA LPE program to extract the parasitic parameters of the circuit, and the LPE program generate a netlist file LSPICE.DAT. I would like to know how to use spectre to simulate the netlist file? I added the content of LSPICE.DAT to the input.scs file, and run simulation, but the simulator did not accept the spice format netlist. How can i do ? Appreciate your help.
Use "simulator lang=spice" command for SPICE based netlist or use SPICE netlist as include. For file with extension .scs preprocessor uses comand "simulator lang=spectre".
For more reference look "SPICE Compatibility" section of Spectre Circuit Simulator User Guide.
A further question would like to know is how to plot both waveforms of pre-layout simulation and post layout simulation in the same window, so as to compare the difference?
