11.4 ChipScope - IBERT GTH - ERROR:sim - Error: ngdbuild failed on prime_top. ERROR:ConstraintSystem:58

Description

When I try to generate a GTH IBERT, I see the following error in Coregen:

ERROR:sim - Error: ngdbuild failed on prime_top. ERROR:ConstraintSystem:58 - Constraint <NET

How do I work around this issue?

Solution

To work around this issue, change the component name. Using "prime_top" as a component name will cause this issue. This issue will be resolved in Coregen 12.1.
