ID:176147 Project requires <number> differential I/O-compatible pins, but target device can contain only <number> differential I/O-compatible pins

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 differential I/O-compatible pins than the device can contain.

ACTION: Reduce the number of differential I/O-compatible pins in the project or select a larger device.
