ID:169007 Current density too high in I/O bank <name> -- pins combined exceed the limit (<number>.<number> mA) by <number>.<number> mA

CAUSE: You made pin assignments in the specified range of pads, but some of the pins are too close together. The specified I/O bank draws a current that exceeds the maximum by the specified amount. The device can drive only a limited amount of current to each I/O bank. Click the + icon to display details about the specific pins, type, location, and I/O standards used in the specified I/O bank.

ACTION: Reassign some pins to reduce the current density or assign some pins to use an I/O standard with a lower current. To display I/O banks, open the Chip Planner and turn on I/O bank display in the Layers Settings dialog box.
