ID:171146 Partial reconfiguration region "<name>" has <number> design partitions assigned to it, but only one partition is supported.

CAUSE: You attempted to compile a design with the incorrect region assignments. The specified region is a partial reconfiguration region and therefore may contain only a single design partition.

ACTION: Create a new partial reconfiguration region for every design partition for which you want multiple personas, and then try to compile the design again.
