In-field self-test controller for safety critical automotive use cases

A method, comprising:

• storing a first test pattern that includes test subpatterns in a memory such that each of the test subpatterns includes test vectors and the test vectors in each of the test subpatterns correspond to a different test core of a plurality of test cores;
• storing configuration parameters that indicate a subset of the plurality of the test cores that are test enabled in configuration registers;
• uploading the first test pattern from the memory with a memory data component;
• and
• decoding the test vectors in a subset of the test subpatterns that correspond to the subset of the plurality of the test cores that the configuration parameters indicate are test enabled with the memory data component.

A non-transitory computer-readable medium (CRM) storing computer executable code, comprising code to:

• store a first test pattern that includes test subpatterns in a memory such that each of the test subpatterns includes test vectors and the test vectors in each of the test subpatterns correspond to a different test core of a plurality of test cores;
• store configuration parameters that indicate a subset of the plurality of the test cores that are test enabled in configuration registers;
• upload the first test pattern from the memory with a memory data component;
• and
• decode the test vectors in a subset of the test subpatterns that correspond to the subset of the plurality of the test cores that the configuration parameters indicate are test enabled with the memory data component.
