Unlike catastrophic failures that simply have incorrect steady-state logic values at the circuit outputs, delay faults change the shape of the output waveforms by moving the signal transitions in time. Therefore, since the output waveforms contain information about the circuit delays, instead of only latching the outputs at the sampling time, the output waveforms between samples are analyzed as well. Two classes of output waveform analysis are discussed. In the first technique, the output waveform is observed for any changes after the sampling time, since in a fault-free circuit, the outputs are expected to have stabilized at the desired logic values. In the second technique, information is extracted from the faulty and fault-free waveforms before the sampling time, and compared for any differences. Circuits for the waveform analyzers are presented to show that the method is feasible, and experimental results are given.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

For the data path portion, the hierarchy of the design is exploited and the dependence on the gate level information is relieved. For the conb’oi faults, gate level algorithms are incorporated with high level approaches to excite the fault and differentiate the fault effect to primary outputs. Due to the fault collapsing effect arid the fault differentiation process, several data types have been defined for the manipulation alf all possible fault e€fects. A functional equivalent model is used for sequential modules, which makes this technique extendable beyond the register-transfer level. The backtracking mechanism used in the control unit has been carefully modified to ensure a complete finite space searching. Some experimerrtal results are presented to show the effectiveness of this approach.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

On the other hand, for high density EPROMs, implementing column redundancy scheme is of vital importance in order to obtain a reasonable yield, as inter-connection design rules are limiting the cell size. However, the conventional column redundancy scheme was not very efficient, because the test circuits did not work well for one of the most dominant failures on miniaturized cells. This paper proposes a new test algorithm, multi-step stress test to solve the problem. The concept has been applied to an actual 16Mbit EPROM, and the yield has been improved to almost double that at the time of the initial developing stage.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

Also fault diagnosis benefits from this knowledge as it allows fast dropping of undistinguishable faults. Equivalent faults are generally identified by mean of a structural analysis of the circuit. Functionally equivalent faults are not considered as their identification is computationally too expensive for real circuits. This paper presents new theorems about functional fault equivalence and dominance. They provide a constructive basis upon which a functional fault collapsing algorithm is built. Application to a set of benchmark circuits establish that identification of functionally equivalent faults is feasible, and that their number may be a not negligible fraction of the faults in a circuit. Results apply both to combinational and synchronous sequential circuits.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

The errors can arise due to failed components (resistors, capacitors, opcrational amplifiers, etc) or simply due to line opens and shorts. A failed component is one whose value has changed due to a harsh environment (heat, etc) or due to drift or one which no longer performs its intended function (such as a shorted capacitor). The error detection is performed by a small amount of additional circuitry whose inputs are tapped directly from the outputs of all the operational amplifiers that compose the circuit on which error detection is to be performed. The sensitivity of the error detection circuitry to errors in the component values can be easily adjusted. The basic idea is to use continuous matrix chechums for error detection. This is possible because the function of an analog or switched-capacitor state variable system can be represented mathematically by a set of matrices to which checksum codes can be applied.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

We introduce a theory of propagation for modules and circuits which can be used for hierarchical test generation and design for testability. The propagation characteristics of a module - whether it can be sensitized to propagate some or all possible fault effects on an input bus - are represented by structures called ambiguity sets. Algebraic operations are performed on ambiguity sets to determine the propagation characteristics of multi-module circuits. We show how this propagation theory is used in test generation and also to aid in designing circuits suitable for high-level test generation.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.
