ID:186104 Project requires <number> GXB receiver channels, but the target device can contain only <number> GXB receiver channels because <number> quads are disabled by an 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 have an I/O coupling problem due to user I/O pin assignments.

ACTION: Modify the design to reduce the number of GXB receiver channels in the project or select a larger device.
