Generating netlists

CLI

Use cb_netlist to generate a netlist from an example:

cb_netlist sw130 circuitbrew.examples.inv hspice all

If your have your own file in a subdirectory mine/logic.py in your current working directory:

cb_netlist sw130 mine.logic hspice all

The general arguments are:

• techfile: only Skywater 130 is publicly released, although it's trivial to write your own
• module: Module that will be instanced
• output format: Only hspice for now, although verilog is planned
• flow steps: Only all for now.

Output

The output goes by default into ./output. In this directory you will see all the files required for simulation:

output/
   top.sp
   hspice_clk.va
   template_0_hspice_src.va
   template_0_hspice_bucket.va

You can run hspice top.sp (or finesim or whatever your simulator of choice is).
