Abstract
Approaches for protecting design information are disclosed. In one approach, a request for an IP core from an integrated circuit device is received, and the request includes identification information. An identifier range is determined from the identification information. The identifier range includes a plurality of unique device identifiers identifying a plurality of integrated circuit devices that are allowed to receive the IP core. The identifier range is downloaded to the integrated circuit device, which evaluates whether or not a unique device identifier that is stored on the integrated circuit device is within the downloaded identifier range. The IP core is programmed into the integrated circuit in response to the unique device identifier that is stored on the integrated circuit device being within the downloaded identifier range.
