5.6.2.1.2. Defining Preset Pin Assignments in a Pin File

Alternatively, you can specify the pin assignments in a Pin Constraints File (.tcl), which can be more efficient for projects with many ports. You specify this .tcl file as the Pin Constraint File on the Pin Assignments tab, and then click Load Pin. The Pin Location and IO Standard update per the loaded pin assignments.

The following shows the contents of an example Pin Constraints File (.tcl):

set_instance_assignment -to "led_export[1]" -name IO_STANDARD "1.2 V" 
set_location_assignment -to "led_export[1]" "PIN_D31" 
set_instance_assignment -to "led_export[2]" -name IO_STANDARD "1.2 V" 
set_location_assignment -to "led_export[2]" "PIN_A30" 
set_instance_assignment -to "led_export[3]" -name IO_STANDARD "1.2 V"
