  • Protection of electronic designs
    Patent number: 11232219
    Abstract: Removing protections on a session-key protected design include receiving a double encrypted vendor private key and an encrypted session key. The double encrypted vendor private key is decrypted into a single encrypted vendor-private key using a user private key, and the single encrypted vendor-private key is decrypted into a vendor private key using a vendor pass phrase. The encrypted session key is decrypted into a session key using the vendor private key, and the session-key protected design is decrypted into a plain design using the session key.

  • Message filtering for electronic design automation systems
    Patent number: 9824170
    Abstract: Message filtering may include, during a first processing phase of a design specified in source code, creating a filter table including message filters and storing the filter table in a memory using a processor. Each message filter may specify a message criterion and an object identifier of the design. During a subsequent processing phase of the design, received messages may be compared with the message filters of the filter table using the processor. Responsive to determining that a selected message matches a message criterion and an object identifier of a selected message filter, the message may be suppressed using the processor.
