(NOTE: This answer record is only a good match for your problem if the string "Duplicate object found" appears in the error messages.)



The error is related to logic replication that incorrectly creates duplicate names. The problem is most likely to occur in Synplify designs because Synplify and logic replication use similar naming conventions.

This problem is fixed in the latest 4.1i Service Pack, available at:
The first service pack containing the fix is 4.1i Service Pack 3.


You can also work around this problem by using the "-l" switch to disable logic replication.
