发明名称 Apparatus and method for licensing programmable hardware sub-designs using a host-identifier
摘要 Methods and apparatuses for enforcing terms of a licensing agreement between a plurality of parties involved in a particular hardware design through the use of hardware technologies. According to one embodiment, a hardware sub-design includes a license verification sub-design that is protected from user modification by encryption. In one embodiment, a license is generated based on a trusted host identifier within an external hardware device. In one embodiment, each trusted host identifier is unique, and no two integrated circuits share the same trusted host identifier. In another embodiment, the integrated circuit is a field programmable gate array or an application specific integrated circuit. In one embodiment, a license determines how long the hardware sub-design will operate when the hardware sub-design is implemented within an integrated circuit having a trusted host identifier.
