Getting started
See install instructions in top-project.
Generate a layout
Generate a layout from a SPICE netlist which includes the transistor sizes:
- --output-dir: Directory which will be used to store GDS and LEF of the cell
- --tech: Python script file containing design rules and technology related data
- --netlist: A SPICE netlist containing the netlist of the cell as a sub circuit (
.subckt). - --cell: Name of the cell. Must match the name of the sub circuit in the SPICE netlist.
mkdir mylibrary
lclayout --output-dir mylibrary --tech examples/dummy_tech.py --netlist examples/cells.sp --cell AND2X1
Adapting design rules
Design rulesi and technology related data need to be encoded in a Python script file as shown in examples/dummy_tech.py.
