Abstract
An on-chip memory diagnostic (OCMD) circuit may instruct a set of built-in self-test (BIST) engines to execute BIST on memories associated with the set of BIST engines. Next, results of executing BIST on the memories may be received from the set of BIST engines. A set of memory failures may then be identified in the memories based on the results. Next, one or more BIST engines in the set of BIST engines may be instructed to collect diagnostic data for each memory failure. A set of diagnostic data may then be received for the set of memory failures. Next, the set of diagnostic data may be stored in an on-chip data container. The set of diagnostic data may then be provided via a communication channel.
