Steps for feature extraction:

1. Put your files (DEF, other reports from Innovus) in directory under ./data.

   Put LEF files in ./LEF.

2. Modify the arguments in process_data.py to match your path.

   Modify the function read to call functions and get features.

Supported Features	Function
Routability Features
macro_region	read_place_def
congestion_early_global_routing	read_eGR_congestion
congestion_global_routing	read_route_congestion
cell_density	compute_cell_density
RUDY/RUDY_long/RUDY_short/pin_RUDY/pin_RUDY_long	get_RUDY
DRC	get_DRC
IR Drop Features
power_i/power_s/power_sca/power_all/power_t/IR_drop	get_IR_features
Graph Features
pin_positions	read_route_pin_position
instance_placement_micron/gcell	read_instance_placement

3. Start feature extraction

python process_data.py

The results are in ./out

4. Visualization (optional)

Modify the arguments in vis.py to match your path, and

python vis.py

The results are in ./images
