## CREATE VA
############

## The following steps are based on the sample design where there're 3 power domains so three voltage areas to be created.
## We'll use tool to decide locations for voltage area so -coordinate is not used
## Please change the value of guard_band and target_utilization as needed  
## GUI: You can also use the GUI to create voltage areas interactively: Menu/Floorplan/Create Voltage Area
## GUI: If you're running it with GUI, please turn on display options for voltage area
#	gui_set_setting -window [gui_get_current_window -types Layout -mru] -setting showVoltageArea -value true
if {$PD1 != ""} {create_voltage_area -guard_band_x 2 -guard_band_y 2 -power_domain $PD1 -target_utilization 0.7}
if {$PD2 != ""} {create_voltage_area -guard_band_x 2 -guard_band_y 2 -power_domain $PD2 -target_utilization 0.7}
if {$PD3 != ""} {create_voltage_area -guard_band_x 2 -guard_band_y 2 -power_domain $PD3 -target_utilization 0.7}
if {$PD4 != ""} {create_voltage_area -guard_band_x 2 -guard_band_y 2 -power_domain $PD4 -target_utilization 0.7}

## Suggestions:
## You can use edit tool bar to further refine voltage area, for example, stretch or move it
## You can also do remove_voltage_area -all to remove all of them and start from scratch
## You should always check if voltage area locations suit your needs before you continue to next step
