#                         PRE-PARTITION PLUG-IN 
##################################################################################
#
# This plug-in script is called before partitioning in the run_partition.tcl script.
#
# - Assign partition pins
# - Set pin-placement parameters for pin-assignment:
#     - pinDepth, to avoid min-area violations when 
#        DRC is run at the partition-level
#     - pinPitch and pin-layers set to single layer 
#       for each side (T/B/L/R)
# - Fix the pin locations after assignment
