Vol: 47(61) No: 2 / June 2002 The C-testability Analyze of the SuperBlock Carry-Lookahead Adder (SBCLA) Daniela E.

Our already published results [5][6][7], together with the Ctestable concept, are very important in testing other kinds of practical adders, which includes cells with CLA units. So, by applying the C-testability concept which is presented in [3][8] we present a method for identifying a minimal complete set of test vectors for detecting all single stuck-at faults for the Superblock Block Carry-Lookahead Adder (SBCLA)), together with our results.
