ABSTRACT:
Methods and structures for design security in configurable devices are described. In some embodiments, a configurable device may be placed in an unsecured mode allowing for access to configuration data and other diagnostic functions during development and production phases. Once the device is finalized, it may be placed in a secure mode that disables a configuration path and enables a bypass path, thereby securing the configuration data. In some embodiments, the configurable device may be a programmable logic device, such as a complex programmable logic device.
