read SmartSpice netlist and control, generate python script.
arguments:
- netlistdir
directory where netlist *.net has been produced
- testbench
netlist prefix
- check=False
if True, produce check files for debugging
- postlayoutdir=None
directory with post-layout extractions
procedure:
- create a top-level schematic in Gateway
- check all to detect any issues
- in simulation mode, check signals to be saved the schematic must be closed to have a *.crb file be generated
- edit/modify the control file
- simulation->create netlist
- close the schematic so that *.crb file is generated
- run create_sspice_script <testbench> (fill in parameters)
- creates <testbench>.py
- modify the python script and use to run simulations
