A method and Dual Interlocked Storage Cell (DICE) latch for implementing
enhanced testability, and a design structure on which the subject DICE
latch circuit resides are provided. DICE latch includes an L1 latch and
an L2 latch are 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.
