A programmable logic device can include a logic core in low power mode, a source input/output (I/O) bank including at least one source I/O pin, wherein the source I/O bank operates in normal operating mode, and a destination I/O bank including at least one destination I/O pin, wherein the destination I/O bank operates in normal operating mode. The programmable logic device also can include a bypass routing bus coupled to the source I/O bank and the destination I/O bank, wherein the bypass routing bus detects an I/O signal from the source I/O pin, responsively generates a bypass signal that is provided to the destination I/O bank and, responsive to the bypass signal, generates an output bypass signal on the destination I/O pin.
