2014.2 Partial Reconfiguration - False pr_verify error (ERROR: [Constraints 18-887] HDPRVerify-04) occurs


After completing route_design with a reconfigurable module, I export a checkpoint, named full_routed_RM1.dcp.
Then I update the reconfigurable module to blackbox and export another checkpoint, named full_RM1_black_box.dcp.

When I run the pr_verify command for the above 2 .dcp files, I get the following error which shows that the number of HD.RECONFIGURABLE instance is zero.

ERROR: [Constraints 18-887] HDPRVerify-04: the number of HD.RECONFIGURABLE instance is 0 in design check point 
implement/full_routed_RM1.dcp, yet it is 0 in design check point implement/full_RM1_black_box.dcp. 
Both check points must have exactly the same number (non-zero) of reconfigurable instances

This is a false error, I can still find the HD.RECONFIGURABLE instance in the design. 


The issue is fixed in The 2014.3 release of Vivado Design Suite.
