2.1.2.1.1. Specifying Multi-Dimensional Bus Constraints
For example, you can specify the following assignment to apply a constraint to all bits in the reg [31:0] r [0:2][4:5] three-dimensional bus:
set_instance_assignment -name PRESERVE_REGISTER ON -to r
The constraint then applies to all bits r: [0][4][31], r[0][4][30], … , r[1][5][0].
