Abstract
A clock tuning system and method for a data processing system with enhanced timing failure diagnostics and unlayering capabilities. Both common and individual phase adjusting capabilities ensure programmable tuning of clock pulses distributed throughout a computer system, thereby facilitating isolation of timing margin failure to specific clock signals or enhancing system performance by shifting timing margin between logic paths. Both single-clock and dual-clock data processing are discussed, as well as clock tuning embodiments for each.
