ABSTRACT:
A binary comparison circuit in which the comparison of individual bits of binary signals can be overridden, with the comparisons of the remaining non-overridden bits determining logical equivalence of the binary signals. This enables the binary signals being compared to be analyzed when they are not fully logically equivalent. In the preferred embodiment, the comparisons of all but the least significant bit are overridable. The circuit may be constructed by programming PAL (Programmable Array Logic) devices.
