Integrated circuits where components are activated based on essential characteristics

摘要

A fixed logic integrated circuit is disclosed. The integrated circuit includes a unique code generator (3) configured to generate a code (4) having a value inherent in the integrated circuit, and a registration pattern (6) based on the unique code (4). And a registration pattern generator (5) configured to generate. The integrated circuit is configured to send a registration pattern (6) to the external registration device (2) and receive enable data (7) from the external registration device. Optionally, the integrated circuit may include a memory (8) for storing remotely generated enable data (7). The integrated circuit includes a configuration file generator (9) configured to generate configuration data (10) using remotely generated enable data (7) and unique code (4), and configuration data (10 A feature activation module (11) configured to activate and / or disable the integrated circuit feature (13) and / or customize the integrated circuit.
