6.3i Modular Design - "FATAL_ERROR:Ncd:nc_isetfactory_imp.c:735: - Active module components are missing .... "


Keywords: MAP, implementation, LOC

Urgency: Standard

General Description:
My design contains LOC constraints on all of the components in my active module. When I run MAP on my active module, the following fatal error is reported:

"FATAL_ERROR:Ncd:nc_isetfactory_imp.c:735: - Active module components are
missing. 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
"WebCase" link at http://support.xilinx.com"


This error indicates that the Area Group is empty. In ISE 6, when a LOC constraint is placed on an instance that is part of an Area Group, it is no longer a member of that Area Group. If all the logic is LOC'd, then the Area Group is empty and the above error is issued.

In ISE 7.1, if the LOC constraint on the instance is within the Area Group range, the instance will retain membership in the Area Group.

To work around this issue, leave at least one item in the Area Group.
