Flat Netlist Files
Mixed-signal software creates a number of netlist files and directories in processing flat
netlists. For descriptions of these files and directories, see the appropriate category below.
Sample analog and digital flat netlists are also provided.
The final digital netlist--called
--is used by the Verilog simulator. The file is in flattened
form, containing only primitive digital instances.
To display the final digital netlist
From the Simulation window, choose Simulation Netlist Create Final.
The final analog netlist is in flattened form, containing only primitive analog instances. This
file is used by the circuit simulator. You can also use this file to run mixed-signal simulation
outside of the mixed-signal circuit design environment. The final analog netlist file resides in
