Abstract
A smaller mask programmable gate array (MPGA) device derived from a larger field programmable gate array (FPGA), comprising: a layout of transistors and a plurality of interconnect layers substantially identical to a smaller region of the FPGA; and input/output pads matching a subset of the input/output pads of the FPGA; wherein, a design that is mapped to said smaller region of the FPGA device using said subset of input/output pads by a user programmable means can be identically mapped to the MPGA by a hard-wire circuit. Such a gate array further comprises a mask programmable metal-circuit in lieu of a user programmable configuration circuit of the FPGA; and a logic block to input/output pad connection in lieu of a logic block to a register at the boundary of said smaller region to an input/output pad connection of the FPGA.
