Rule Deck Testing

The Makefile and the run_test_case.sh script makes multiple tests of the LVS rule deck of SKY technology.

Tests

Usage

    make <target>

    targets:
        "all                   (the default if no target is provided                 )"
        "test_lvs_main         (To run main lvs regression for all devices           )"
        "test_lvs_collective   (To run collective lvs regression for all devices     )"
        "test_lvs_connectivity (To run connectivity lvs regression for all devices   )"
        "test_lvs_sc           (To run standard cells lvs regression for all devices )"

Example:

    make test_lvs_main

Options

all (the default if no target is provided, runs the below ) test_lvs_main (To run main lvs regression for all devices ) test_lvs_collective (To run collective lvs regression for all devices ) test_lvs_connectivity (To run connectivity lvs regression for all devices ) test_lvs_sc (To run standard cells lvs regression for all devices )

Testing Outputs

Final results will appear at the end of the run folder.

The output files are :

1. All extracted netlist (<tested_circuit>.cir).

2. Database file (<tested_circuit>.lvdb) for comparison results. you could view it on your file using klayout.

3. Log file of each circuit that had run.

4. May contain .cdl and .gds if test_lvs_sc target is used.
