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

Description

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
"memc?_wrapper_inst/memc?_mcb_raw_wrapper_inst/gen_term_calib.mcb_soft_calibr
ation_top_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL" TIG;>
[example_top.ucf(38)]: NET
"memc?_wrapper_inst/memc?_mcb_raw_wrapper_inst/gen_term_calib.mcb_soft_calibr
ation_top_inst/mcb_soft_calibration_inst/DONE_SOFTANDHARD_CAL" does not match
any design objects.

Solution



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.
