MIG 3.7 Spartan-6 MCB - Failure in NGDBUILD due to improper TIG in constraints file


There is an issue with MCB designs where they are failing due to an incorrect hierarchy path being used in a TIG in the UCF file.

Verilog example designs are failing due to an NGDBUILD error caused by this improper TIG constraint.

ERROR:ConstraintSystem:58 - Constraint <NET
ation_top_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL" TIG;>
[example_top.ucf(38)]: NET
ation_top_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL" does not match
any design objects.


The above issue can be solved by changing the TIG to:

NET "memc?_wrapper_inst/mcb_ui_top/mcb_raw_wrapper_inst/gen_term_calib.mcb_soft_calibration_to
p_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL" TIG;

This issue has been fixed in MIG 3.8.
