Explains how to test GF180nm LVS rule decks.
📁 testing ┣ 📜README.md This file to document the regression. ┣ 📜Makefile To make a full test for GF180nm LVS rule deck. ┣ 📜run_regression.py Main regression script used for LVS testing. ┣ 📁testcases All testcases used in LVS regression.
You need the following set of tools installed to be able to run the regression:
We have tested this using the following setup:
run_regression.py (--help| -h) run_regression.py [--device_name=<device_name>] [--mp=<num>] [--run_name=<run_name>]
Example:
python3 run_regression.py --device_name=MOS --run_name=mos_regression
--help -h Print this help message.
--mp=<num> The number of threads used in run.
--run_name=<run_name> Select your run name.
--device_name=<device_name> Target specific device.
To make a full test for GF180nm LVS rule deck, you could use the following command in testing directory:
make all
You could find the regression run results at your run directory if you previously specified it through --run_name=<run_name>. Default path of run directory is unit_tests_<date>_<time> in current directory.
📁 unit_tests_<date>_<time> ┣ 📜 unit_tests_<date>_<time>.log ┣ 📜 all_test_cases_results.csv ┗ 📜 rule_deck_rules.csv ┗ 📁 <device_name> ┣ 📜 <device_name>_lvs.log ┣ 📜 <device_name>.gds ┣ 📜 <device_name>.cdl ┣ 📜 <device_name>_extracted.cir ┣ 📜 <device_name>.lvsdb
The result is a database file for each device (<device_name>.lvsdb) contains LVS extractions and comparison results. You could view it on your file using: klayout <device_name>.gds -mn <device_name>.lvsdb, or you could view it on your gds file via marker browser option in tools menu using klayout GUI.
You could also find the extracted netlist generated from your design at (<device_name>.cir) in your run directory.
