10.1 ISE - Adding an EDIF (.edn) file with partitions causes Project Navigator to fail

Description

Adding an EDIF file with PARTITIONS to a Project Navigator Project causes Project Navigator to fail with a segmentation fault.

If an EDIF file of the same design is created without PARTITIONS and added to the project, everything is fine.

If I remove the PARTITIONS statements from the EDIF file, it is fine.

Solution

There is an issue with the Xilinx custom EDIF parser which can cause this problem. The parser expected the cell name to be in the following formats:

<cell qualifier>

<library>.<cell qualifier>

<library>.<package>.<cell qualifier>

However, if the cell name (cell qualifier) has a "." period separator in the name, this causes the parser to overflow an array which expected three items.

This problem has been fixed in the latest 10.1 Service Pack available at:

The first service pack containing the fix is 10.1 Service Pack 2
