Abstract

The authors have developed an automatic system called CONDOR (concurrent error checker diagnosability analyzer) which quantitatively evaluates the effectiveness of the arrangement of error detection circuits and automatically generates a fault dictionary based on the computer logic design data file. The CONDOR diagnosis support was applied to a large-scale logic computer with more than a million gates. It designed the diagnosis facility for the large-scale computer quickly by simplifying the logic design data. The labor required for generating a fault dictionary can be reduced by 90% or more. Also, the fault-locating accuracy of the fault dictionary was increased from 97% to 100%
