Application: Simulation model authentication (Patent ID: US20240095431A1)

The patent filed by Taiwan Semiconductor Manufacturing Co Ltd discloses a method for using a semiconductor device characterization description in circuit simulation management. The method involves accessing the characterization description, a starter code, generating a model authentication code (MAC) based on these inputs, and transmitting them to a model interface (MI). The MI then compares the MAC with a stored characterization description to allow or disallow simulation based on the match.

Furthermore, the method includes generating multiple MACs based on different starter codes, accessing expiration dates for the characterization description, and determining if the description has expired. The system also involves a model generation system and a MI that communicate to facilitate the simulation process. The MI is responsible for comparing MACs, communicating with a simulator, and making decisions on allowing or disallowing simulation based on the authentication codes and expiration dates. This approach ensures secure and controlled access to semiconductor device characterization descriptions for accurate circuit simulations.
