General Description: MAP fails during the "Running cover..." phase with the following errors:
"EXCEPTION:Xdm:xdm_bagt.h:431:$Id: xdm_bagt.h,v 1.37 2001/02/27 20:16:45 jdl Exp $ - Duplicate object found name='/tcc_ocx/FRAGCOVERED/tcc_ocx/a\/reg_rd_Q_3_1' (XDM_BLOCK) in parent 'XDM_OBJECT' (XDM_OBJECT)"
"FATAL_ERROR:Map:Port_Main.h:116:1.17 - This application has discovered an exceptional condition from which it cannot recover. Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com"
(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.
