Abstract
The present disclosure generally relates to using built-in self-test (BIST) for on-chip error detection. In some aspects, a method includes receiving information about one or more parameters for a built-in self-test (BIST) operation, generating a nonce for each iteration of the BIST operation according to the one or more parameters, and computing a hash value for each iteration of the BIST operation using the nonce as an input to a cryptographic hash function. The method further includes transmitting, to multiple hash engines, information about the nonce and the hash value for each iteration of the BIST operation. The method further includes receiving, from each hash engine, a response with information indicating a number of correct results computed by that hash engine. The method further includes comparing the indicated number of correct results to an expected number of correct results for the BIST operation.
