+The netlist compare algorithm is basically a backtracing algorithm. +With ambiguous nets, the algorithm picks possible net pairs and +tries whether they will make a good match. Following the deduction +path for this nets may lead to further branches if more ambiguous +nets are encountered. To avoid combinational explosion, the maximum +branch complexity is limited to the value configured with this +function. The default value is 500 which means not more than +500 combinations are tried for a single seed pair. For networks +with inherent ambiguity such as decoders, the complexity +can be increased at the expense of potentially larger runtimes. +The runtime penality is roughly proportional to the branch +complexity. +
