5.1i Incremental Design - Carry logic is not wrapped when it does not fit in an area group during PAR

General Description:

Previously, when a carry chain was too long for an area group, the carry chain was broken up so that the design could be placed and routed. In the initial 5.1i software release, an error is issued and the design is not placed and routed.
