Described are apparatuses and methods for detecting or repairing minimum-delay errors. The apparatus may include a minimum-delay error detector (MDED) to receive a clock signal and a data path signal and to detect a minimum-delay error (MDE) in the data path based on the received data path signal and the clock signal. The MDE may be repaired by adjusting one or more regional clock buffers coupled to the MDED. Further, the apparatus may include minimum-delay path replicas (MDPRs) used for detecting and repairing MDEs during normal system operations. Other embodiments may be described and/or claimed.
