The Critical Cycle Time objective calculates signal timings which give the shortest cycle time that allows the junction to operate within capacity. Usually, therefore, the PRC for this objective should be precisely zero. However, when using integer phase timings, rounding effects can lead to the PRC being slightly less than zero. We expect to improve this for future releases of the program but, in the meantime, to obtain more accurate results, go to the View>Options screen and turn off the Integer Phase Timings option.
