Abstract

The present invention provides architectures for hybrid integrated circuits and methods for producing these hybrid integrated circuits that contain both field programmable gate arrays and mask programmable gate arrays, a form of application specific integrated circuits. Methods for producing an integrated circuit that is field programmable as well as mask programmable include the steps of: designing wafer bank layers and finishing layers, where the wafer bank layers provide a plurality of selectable functional blocks; fabricating said wafer bank layers; designing mask programmed interconnect layers for said integrated circuit, where the interconnect layers interconnect selected ones of the plurality of functional blocks from the wafer bank layers; fabricating the interconnect layers on the wafer bank layers; and fabricating the finishing layers on the interconnect layers to produce the integrated circuit. Architectures for these integrated circuits can contain a field programmable gate array that is integrated with a mask programmable gate array in a ring structure.
