Main frame diagnosis support system

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%. >
