## Variable defaults and legal values based on ICC B-2008.09
## N/A means not a create_fp_placement option or parameter
## "Brief_Description" column below intends to give you quick reference of what the option does. 
## Please refer to man page of create_fp_placement or set_fp_placement_strategy for more details.

# Legend			Default	<Range>	  (Correspondent command) Brief_Description

# N macro orientation		automatic <automatic,all,N> (set_fp_placement_strategy -macro_orientation)
# O sliver size			10  	<a positive number> (set_fp_placement_strategy -slive_size) 
#			 			   minimum channel size allowing std cells to be placed, tool default is 0

# Q io net weight		1  	<a positive number btw 0-10> (set_fp_placement_strategy -IO_net_weight) net weight on nets connected to IOs
# R plangroup interface net wt	1  	<a positive number btw 0-10> (set_fp_placement_strategy -plan_group_interface_net_weight) net weight on interface nets of exclusive plan groups
# S VA interface net wt		1  	<a positive number btw 0-10> (set_fp_placement_strategy -voltage_area_interface_net_weight) net weight on interface nets of voltage areas
#						   can be used to place level shifters close to boundary of VA
# T VA net weight level shifter off  	<on,off>  (set_fp_placement_strategy -voltage_area_net_weight_LS_only) 
#						   makes U only applied to nets connected to level shifter or isolation cells

# Tips
# The above predefined runs are only switching C,D,E,F,and G options which should give you good sarting point.
# Feel free to customize other options. Option B is only for tracking purpose. You can rename it whatever you want.
# Use # to comment out runs you don't want or simply remove them. Each run is independent like a tcl command.
# You can create your own runs and simply append them to the above runs.
