Abstract

Timing errors in computer designs are not uncommon. They tend to be difficult to detect and to cause spurious, seemingly transient behavior. In generations previous to the processor complex, the IBM 3081, timing failures were discovered largely by constructing engineering models and running them very extensively. The advent of LSI, however, obviated the feasibility of this mode of operation, because of the complexity of the design and because of the prohibitively large delay in the design cycle in making corresponding Engineering Changes, to account for every detected timing fault. Furthermore, it could not be guaranteed by this engineering test procedure that the resulting design and product were devoid of timing faults.
