Abstract:
1. A method for creating a mask-programmed integrated circuit that includes a reprogrammable structure, comprising: (a) receiving a description of circuit functionality specified by a user for implementation with the mask-programmed integrated circuit, the description of circuit functionality including a description of non-reprogrammable functionality and descriptions of a plurality of different programmable functionalities to be later programmable into the reprogrammable structure of the mask-programmed integrated circuit to implement one of the different programmable functionalities; (b) automatically modeling the reprogrammable structure to be capable of alternatively implementing each of the programmable functionalities; (c) performing physical layout for the entire mask-programmed integrated circuit, including the reprogrammable structure as well as circuitry to accommodate the non-reprogrammable functionality,
