Abstract
A programmable array (10) includes an array (11) of transistor cells, output cells (26, 28, 32, 34), and two internal power busses (17, 18) which are coupled to the array (11) of transistor cells. The programmable array also includes eight output power busses (35, 36, 37, 38, 41, 42, 43, 44) coupled to the output cells (26, 28, 32, 34). The two internal power busses (17, 18) are coupled to two corresponding output power busses (35, 36) via two coupling switches (55, 56). Further, the output power busses (35, 36, 37, 41, 42, 43, 44) are coupled to each other via eight switches (45, 46, 47, 48, 51, 52, 53, 54). Different power bus routings of the programmable array (10) are realized by controlling the two coupling switches (55, 56) and the eight switches (45, 46, 47, 48, 51, 52, 53, 54).
