14.x Constraints - Does the CLOCKREGION based AREA_GROUP constraint affect I/O placement?


Can I use AREA_GROUP xx RANGE = CLOCKREGION_XnYn to constrain the location of I/O?


CLOCKREGION based Area Group does not include I/Os.

To constrain the specific I/Os to a clock region, use the LOC constraint with a specific location or a bank.
