## ICC Design Planning RM
## proc_explore.tcl: performs explore run with vitual flat placement, PNS/PNA, IPO, and proto route
##                   the procedure "dp_explore" is used by icc_dp_scripts/explore.tcl
## Version B-2008.09   
####################################################################################################

# =============================================================================================
# Variables that usually may not need to be changed during exploration
# You can change the setting here and will affect all explore runs
# =============================================================================================

# =============================================================================================
# 		Procedure
# =============================================================================================
# This procedure is to have all arguments 
# Usage is like the following:
# dp_explore run0 default off low  on  off off off 512 low off "" "" automatic 10 low 1 1 1 off on high
