A method and a Dual Interlocked Storage Cell (DICE) latch implementing
enhanced testability includes an L1 latch and an L2 latch coupled to the
L1 latch. Each L1 latch and each L2 latch includes redundant latch
structures. A separate output is provided with the redundant L2 latch.
The DICE latch includes a Redundant Test Latch Enable (RTLE) input. Each
L1 latch and each L2 latch includes a path selector control in the
redundant latch structures controlled by the RTLE input providing each of
the redundant latch structures in a scan path during a test mode.
