When entering constraints in a for loop from an XDC file, the constraints do not get applied as expected.
XDC constraints are a combination of:
XDC constraints files do not act the same as TCL scripts run through a TCL parser.
Only a subset of Tcl commands are valid in an XDC file.
For this reason, for loops will not function correctly and are not supported in XDC files.
To apply constraints in the form of for loops, generate the constraints with a Tcl script and have it executed in any of the following ways:
