ID:186107 Project requires <number> XGMII state machines, but the target device can contain only <number> XGMII state machines because <number> quads are disabled by I/O coupling problem

CAUSE: You selected a target device for the current project. However, the Fitter cannot place the project in the target device because the project requires more quads are disabled. These quads are disabled because they have I/O coupling problems due to user I/O pin assignments.

ACTION: Modify the design to reduce the number of XGMII state machines in the project or select a larger device.
