# This script runs Circuit Training (CT) Grouping to generate clustered 
# netlist from the Protobuf netlist. For more details please see CT 
# Grouping README (Link: 
# https://github.com/google-research/circuit_training/blob/main/circuit_training/grouping/README.md)
#
# Update the following environment variables to run CT Grouping using 
# this script:
#   1. NETLIST_FILE: Provide the path of the input Protobuf netlist
#   2. HMETIS_DIR: Provide the directory path where the hMETIS executable 
#      files exist.
#   3. PLC_WRAPPER_MAIN: Provide the path of the plc_wrapper_main binary. 
#      This binary is downloaded from CT. Link to the binary:
#      https://storage.googleapis.com/rl-infra-public/circuit-training/placement_cost/plc_wrapper_main
#   4. CT_PATH: Provide the directory path where CT is cloned.
#   5. OUTPUT_DIR: Provide the directory path where to save the final 
#      clustered netlist.
#
# Before launching the script make sure that PHY_SYNTH environment variables
# is set to 1.
