Abstract
An exemplary embodiment of the invention is a method and apparatus for configuring system cycle time in a data processing system with at least one master latch clock generating a master latch clock signal and at least one slave latch clock generating a slave latch clock signal. Timing errors are detected during system hardware testing. Adjustments to the system timing are calculated based on error for at least one of a master latch clock signal and a slave latch clock signal. The on-cycle edge of at least one of the master latch clock signal and slave latch clock signal is adjusted based on the calculations while maintaining a corresponding mid-cycle edge of at least one of the master latch clock signal and the slave latch clock signal.
