intermediate_file_generator

Intermediate file generator for ICCAD 2024 CAD Contest benchmarks

This directory contains Python scripts that generate updated timing values after gate sizing, following the CircuitOps Intermediate Representation (IR) Tables format.

Run the script

Make sure you have OpenROAD built locally. Run the following command to get the updated timing values:

• Add the name of the benchmark with the "--design_name" flag.
• Add the path including the name of your output file with the "--file_path" flag.
• Add the "--dump_csv" flag to get the intermediate files.
  • Add the output directory with the "--dump_path" flag if "--dump_csv" flag is added.

# You can also import the "updated_dataframe_generate" function from the Python file to get the pandas DataFrame
../../OpenROAD/build/src/openroad update_circuitops_properties.py --design_name <design name> --file_path <output file> --dump_csv --dump_path ./

Intermediate file format

<pinName or portName>,<maxcap>,<maxtran>,<pin_tran>,<pin_slack>,<pin_rise_arr>,<pin_fall_arr>,<input_pin_cap>,<output_pin_cap>

<instanceName>,<staticPower>

"output_pin_cap" is the sum of the sink pins' capacitance and the net capacitance.
