A programmable logic device has a plurality of conductors extending around its periphery for use in providing at least some of the signals needed for control of input/output (“I/O”) pins which are also disposed around the periphery of the device. These control signals may include clock signals, output enable signals, clock enable signals, clear signals, or the like. The conductors that thus extend around the periphery are segmented into plural segments that can either be used independently of one another or programmably stitched together and therefore used together.
