Abstract: A programmable logic device verifies that configuration data permissibly programs the programmable logic device. The programmable logic device includes a programmable fabric having partitions to be programmed by the configuration data, a secure device manager that may generate masks based on the configuration data, and a local sector manager. The masks determine that the configuration data is configured to permissibly program the permitted partitions or that the permitted partitions have been permissibly programmed. The local sector manager applies the masks to generate an interleaved result, compares the interleaved result to an expected result, and sends an indication that the configuration data is configured to permissibly program the permitted partitions or permissibly programmed the permitted partitions in response to determining that the interleaved result is the expected result, or sends an alert to stop programming in response to determining that the interleaved result is not the expected result.
