AR# 23993 8.2i EDK - "ERROR:NgdBuild:752 - Line xx in '<design>.ucf': Could not find instance(s) 'dcm_0/dcm_0/DCM_ADV_INST' in the design" - errors can be seen for designs that passed correctly in ISE 8.1i

Description

Keywords: EDK, generate, UCF, VHDL, constraint, NGDBuild, 752, ML$)x, demo, board

After upgrading from 8.1i to 8.2i, EDK users who have UCF location constraints might encounter the following error:

ERROR:NgdBuild:752 - Line 57 in 'system.ucf': Could not find instance(s)
'dcm_0/dcm_0/DCM_ADV_INST' in the design. To suppress this error, specify
the correct instance name or remove the constraint. The 'Allow Unmatched LOC
Constraints' ISE property can also be set ( -aul switch for command line
users ).

What has changed, and how can I fix my design?

Solution

For the specific cause in XST, please refer to (Xilinx Solution 23249)

The DCM INST statements in the existing UCF files for the ML40X platforms
must be modified to include the wildcard (*) character as shown below.

Select the replacement lines for the desired ML40X MicroBlaze (MB)
or PowerPC (PPC) reference design.
