Description
cross connection has an invalid configuration for arg I/O.
The resultant I/O signal arg of cross connection is the same as the cross connection arg.
If you have multiple cross connection causing the same signal to be set, it can cause unpredictable behavior because you have no control over the order in which they are evaluated.
Consequences
This cross connection has been rejected and features relying on this cross connection will not work.
Recommended actions
Make sure that the I/O signal is not assigned to resultant as multiple cross connection.
