ID:184016 There were not enough <gpio_desc> pin locations available

CAUSE: Some or all of the pins in your design could not be placed. This may be because you have too many pins in your design for the chosen device, or some unoccupied pin locations were unavailable due to region constraints or similar reasons.

ACTION: If the affected pins are locked to a region, relax the constraint. Note that pins that are fed by non-global clock signals, such as regional clocks, may impose additional constraints not explicitly specified in your assignments file. Otherwise, you may have to change your chosen device or reduce the number of I/Os in your design.
