Methods for controlling the use of intellectual property in individual integrated circuit devices

摘要

A method for controlling the use of intellectual property (IP) in an individual integrated circuit includes loading data including the IP into the individual integrated circuit, loading an IP license certificate into the individual integrated circuit, the certificate including identification of the IP authorized for the individual integrated circuit, determining inside the individual integrated circuit whether the IP is authorized for the individual integrated circuit, enabling operation of the individual integrated circuit if the IP circuit is authorized for use in the individual integrated circuit, and imposing a penalty on operation of the individual integrated circuit if the IP is not authorized for use in the individual integrated circuit.
