ID:22676 The argument (<constraint argument>) matches bidirectional hierarchical pin '<constraint target>' which will be lost during flattening. In this release, this constraint target is ignored.

CAUSE: The constraint targets a hierarchical pin that is not preserved after flattening because it's bidirectional. In this release, the constraint target is ignored.

ACTION: Specify pin constraints on ports, pins of leaf/partition instances, or on uni-directional hierarchical ports.
