چکیده

In this paper we explore the test complexity of the adder function with respect to the robust path delay fault model. A lower bound of (n 2) for the cardi-nality of a complete test set for a combinational n-bit adder is proven. This result is valid for any adder design known until now. In addition we present a fast O(p n)-time adder that is fully robust path delay fault testable with a test set of size (n 2).

Synthesis of robust delay-fault-testable circuits: theory

Correct operation of synchronous digital circuits requires propagation delays of all sensitizable paths in the circuit to be smaller than a speciied limit. Physical defects and processing variations in integrated circuits can aaect the temporal behavior of a circuit without altering the logical behavior. These defects are called delay faults. In order to design, and especially to synthesize, hi...

Synthesis for Testability Techniques for Asynchronous Circuits

Our goal is to synthesize hazard-free asynchronous circuits that are testable in the very stringent hazard-free robust path-delay-fault model. From a synthesis perspective producing circuits satisfying two very stringent requirements, namely, hazard-free operation and hazard-free robust path-delay-fault-testability, poses an especially exciting challenge. In this paper we present techniques whi...

Multilevel Logic Optimization Transformations used in existing logic synthesis systems are characterized with respect to their testability preserving and testability enhancing properties. A su cient condition for a multilevel unate circuit to be \hazard free delay fault testable" is presented. In contrast to existing results that consider either \single path propagating hazard free robust tests...

On completely robust path delay fault testable realization of logic functions

A large class of Boolean functions, as well as almost all symmetr ic Boolean functions, are shown to have no two-level completely robust path-delay-fault testable ( R P D F T ) realization b y combinational circuits. Exact and asymptotic formulae are derived fo r the number of symmetric Boolean functions which have two-level completely R P D F T realization. To achieve completely R P D F T real...

On Testing the Path Delay Faults of a Microprocessor Using its Instruction Set

This paper addresses the problem of testing path delay faults in a microprocessor using instructions. It is observed that a structurally testable path (i.e., a path testable through at-speed scan) in a microprocessor might not be testable by its instructions simply because no instruction sequence can produce the desired test sequence which can sensitize the paths and capture the fault effect in...
