Abstract

"The generation of fault detection sequences for asynchronous sequential networks is considered here. Several techniques exist for the generation of fault detection sequences on combinational and clocked sequential networks. Although these techniques provide closed solutions for combinational and clocked networks, they meet with much less success when used as strategies on asynchronous networks. It is presently assumed that the general asynchronous problem defies closed solution. For this reason, a secondary procedure is presented here to facilitate increased fault coverage by a given fault detection test sequence. This procedure is successful on all types of logic networks but is, perhaps, most useful in the asynchronous case since this is the problem on which other techniques fail. The secondary procedure has been designed to improve the fault coverage accomplished by any fault detection sequence regardless of the origin of the sequence. The increased coverage is accomplished by a minimum amount of additional internal hardware and/or a minimum of additional package outputs. The procedure presented here will function as part of an overall digital fault detection system, which will be composed of: 1) a compatible digital logic simulator, 2) a set of fault detection sequence generators, 3) secondary procedures for increasing fault coverage, 4) procedures to allow for diagnosis to a variable level. This research is directed at presenting a complete solution to the problems involved with developing secondary procedures for increasing the fault coverage of fault detection sequences "--Abstract, pages ii-iii.
