#                      POST-PRE_CTS PLUG-IN 
##################################################################################
#
# This plug-in is called after optDesign -preCTS from the run_prects.tcl flow
# script.  The user can use this plug-in for:
#
# --------------------------------------------------------------------------------
#     - Secondary power pin routing for low power cells 
#        - State retention flops
#        - Always-on-buffers
#        - Level-shifters
#     - Check the connectivity and geometry on these nets
# --------------------------------------------------------------------------------
# Below are some example commands ...
####################################################################################

####################################################################################
# Secondary power routing for SRPG/AON/LVL cells using nanoroute ...
# It requires vars(secondary_pg,cell_pin_pairs) to be defined in the lp_config.tcl
# --------------------------------------------------------------------------------
# NOTE: In the early stage of the flow (before CTS) if user wants to estimate the
# routing resource impact due to secondary pg pin routing, he can do secondary pg pin
# connection before CTS OR if user enables "vars(route_secondary_pg_nets)" as true in
# OVERLAY/lp_config.tcl then same would be done before the routing stage also.
