A method and apparatus for loading a ring of non-scan latches for a logic
built-in self-test. A logic built-in self-test value is loaded into a
scannable latch from the logic built-in self-test. An override control
signal is asserted in response to loading the logic built-in self-test
value into the scannable latch. A non-scan latch is forced to load the
logic built-in self-test value from the scannable latch in response to
asserting the override control signal. Logic paths in the ring of
non-scan latches are exercised. The non-scan latch is part of the logical
paths. The test results are captured from the logic paths and the test
results are compared against expected test results to determine if the
logic paths within the ring of non-scan latches are functioning properly.
