6.1i Floorplanner - UCF written out by Floorplanner contains elements in an AREA GROUP that do not exist

Description

Keywords: Floorplanner, UCF, range, read, SLICE, TBUF, MULT, BRAM

Urgency: Standard

General Description:
I open my design in Floorplanner and read in my UCF. The UCF read in contains information on area groups with slice ranges. I then tell Floorplanner to write the constraints back to the UCF. However, the output UCF contains information on area groups with SLICE, TBUF, MULT, and BRAM ranges even though the design does not contain these.

Solution

This was caused by a limitation of the tools. This issue has been fixed in a service pack update for the 6.1i software. The service pack containing this fix is SP3.

This problem has been fixed in the latest 6.1i Service Pack available at:

The first service pack containing the fix is 6.1i Service Pack 3.
