A method for analyzing and optimizing a design, such as a circuit design, which relates to the application of at least one optimization procedure, evaluating the benefit and net cost of the optimization procedure and then through the checkpoint manager, recording and reversing changes of the design. The execution and reversal of multiple optimizations may occur in a trial mode followed by evaluation of the executed and reversed designs and then the reinstatement of the best optimization.
