    摘要： A multiplexing device is described. In one embodiment, the multiplexing device includes: a hardwired multiplexer including a plurality of input terminals; a plurality of select terminals; and at least one output terminal, where the plurality of input terminals are coupled to a plurality of block input lines or a plurality of functional element input terminals. In one embodiment, the plurality of input terminals are hardwired to the plurality of block input lines or the plurality of functional element input terminals. In one embodiment, the plurality of select terminals are coupled to a second plurality of functional element input terminals or a plurality of functional element output terminals. In one embodiment, the plurality of block input lines include a plurality of logic array block (LAB) lines, the plurality of functional element input terminals include a plurality of logic element (LE) input terminals, and the plurality of functional element output terminals include LE output terminals. In another embodiment the multiplexing device includes: a hardwired multiplexer including a plurality of data signal input terminals; and a first plurality of LEs including a first plurality of LE output terminals, where the plurality of data signal input terminals are coupled to the first plurality of LE output terminals.
