In case the two sets of activation patterns are mutually exclusive without considering the logic feeding into the activation signals, an activation condition can only be relevant if present in both sets with opposite polarity. This detects pattern-only mutual exclusion by running an additional SAT query before importing the input cone logic. If that is already UNSAT, we remove all non-relevant condition and re-simplify the remaining patterns. In cases of pattern-only mutual exclusion, this will often produce much smaller selection logic and avoid the more costly SAT query that includes the input cones. |
