ID:170020 Project requires <number> general purpose I/O cells, but the selected device can contain only <number> general purpose I/O pins

CAUSE: You specified a target device for the current design. However, the Fitter cannot place all the general purpose I/O cells within the target device because the project requires more general purpose I/O pins than the device contains.

ACTION: Select a larger device or reduce the number of general purpose I/O cells in the design.
