8.1i Map - "FATAL_ERROR:MapLib:basmmplist.c:662:1.11 - remove_by_idx"


When I run Map, the following fatal error occurs: 


"FATAL_ERROR:MapLib:basmmplist.c:662:1.11 - remove_by_idx, target does not match 

idx. Process will terminate. To resolve this error, please consult the 

Answers Database and other online resources at http://support.xilinx.com. If 

you need further assistance, please open a Webcase by clicking on the

How can I avoid this error?


This error can occur when the -bp option (Map Slice Logic into Block RAM) is used with KEEP_HIERARCHY constraints. 


This problem is scheduled to be fixed in 8.2i. In the meantime, you can avoid the problem by not using the -bp option, or by using the -ignore_keep_hierarchy option (Allow Optimization Across Hierarchy) to override KEEP_HIERARCHY constraints.
