Abstract
Methods and systems are provided for dynamically generating a hint set for enhanced reachability analysis in a sequential circuitry design that is represented by a Binary Decision Diagram (BDD). After determining a ranking of the BDD variables, they are sorted in the order of the ranking. The ranking is used to select some of the variables for use in creating hints for more efficiently performing the reachability analysis in a creating an equivalent sequential circuitry design.
