9.1.03i NGDBuild - "FATAL_ERROR:HierarchicalDesignC:PartitionHelper.c:226: - ERROR :IPartitionHelper::IsPartition called with a null block. Process will terminate."


Keywords : FATAL_ERROR , HierarchicalDesignC , PartitionHelper.c:226: , Process will terminate , ISE,9.1, Unknown error message

When I run Translate, an error similar to the following occurs:

""FATAL_ERROR:HierarchicalDesignC:PartitionHelper.c:226: - ERROR :

IPartitionHelper::IsPartition called with a null block. Process will

terminate. For more information on this error, please consult the Answers

Database or open a WebCase with this project attached at


Process "Translate" failed "

I do not have partitions in my design. I do keep hierarchy by setting the keep hierarchy attribute in XST to YES.

How do I resolve this problem?


This is a known issue in ISE 9.1i and has been addressed in ISE 9.2i.

To work around this problem, set the keep hierarchy attribute to SOFT. For more information on the SOFT option, see the ISE Help.
