A programmable semiconductor device comprising a plurality of I/O circuits arranged into blocks includes a routing structure for each block, wherein each routing structure may programmably route signals between its block's I/O circuits and the I/O circuits within the remaining blocks. Each I/O circuit associates with a pin such that each block has a set of pins. A SERDES and a FIFO buffer associate with each block. Each block's SERDES couples between the block's I/O circuits and the block's set of pins. Each FIFO buffer couples between the SERDES and its block's I/O circuits.
