ABSTRACT:
A method for interconnecting sub-functions of metal-mask programmable functions that includes the steps of (A) forming a base layer of a platform application specific integrated circuit (ASIC) comprising a plurality of pre-diffused regions disposed around a periphery of the platform ASIC, (B) forming two or more sub-functions of a function with a metal mask set placed over a number of the plurality of pre-diffused regions of the platform application specific integrated circuit and (C) configuring one or more connection points in each of the two or more sub-functions such that interconnections between the two or more sub-functions are tool routable in a single layer. Each of the pre-diffused regions is configured to be metal-programmable.
