The C-testability analysis of the superblock carry-lookahead adder (SBCLA)

The paper is the result of the authors' activities concerning the testing and the design for testability for computer arithmetic systems. Our results, together with the C-testable concept, are very important in testing other kinds of practical adders, which includes cells with CLA units. So, by applying the C-testability concept 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.
