Reducible registers are determined to optimize a sequential circuit. A screening method tests one or more sets of registers where the registers of each set are assumed to satisfy a logic condition. The tests determine if the logic condition holds. If the logic condition of a set is found to be violated, the registers may be moved to another set having a different logic condition or removed completely. The registers remaining are potentially reducible. The reducibility of the registers is verified via Boolean analysis by verifying the logic conditions of a register set for each register. If a register does not pass verification, it then may be moved to a different set having a different logic condition or removed completely. The sets that pass verification are reducible.
