2014.4 - Critical warning should be reported if register with IOB=TRUE property fail to be placed into an IOB site.


I set IOB = TRUE for both registers driving the OBUFT in XDC.

Because the reset signal of both registers are different, these two registers cannot be packed into IOB at the same time.

A warning should be issued about the register not being packed into IOB.


The issue is being evaluated for future addition of a message.
