10.1 EDK, MPMC v4.00.a - ERROR:ConstraintSystem:58 - Constraint does not match any design objects

Description

When converting a Virtex-4 MIG 2.2 ucf to MPMC using the convert.pl script, the following error occurs. How do I resolve this issue?

"ERROR:ConstraintSystem:58 - Constraint <INST

"*/mpmc0/mpmc_core_0/gen_??_ddr_phy.mpmc_phy_if_0/data_path_00/tap_logic_0/data_tap_inc_1*" AREA_GROUP=data_tap_gp1;>

[system.ucf(92)]: INST

"*/mpmc0/mpmc_core_0/gen_??_ddr_phy.mpmc_phy_if_0/data_path_00/tap_logic_0/data_tap_inc_1*" does not match any design objects."

Solution

Some of the constraints in the error message should have been modified by the convert script. To work around this issue, try to rerun the conversion with an updated script provided in (Xilinx Answer 29261).

This issue is fixed in MPMCv4.03.a, to be released in EDK 10.1, Service Pack 3.
