專利摘要

A device for detecting and correcting timing error and a method for designing typical-case timing using the same is disclosed. The device includes two datapath units connected with first and second multiplexers and two transition detectors. Each datapath unit receives and calculates an input signal to generate a speculation value and a correct value. Then, the speculation value and the correct value are transmitted to the first and second multiplexers and the transition detectors determine whether transition of the outputted speculation value is unstable. If yes, the datapath unit outputting the speculation value is stalled for a period of time for correction, whereby the second multiplexer outputs the correct value. If no, the datapath unit outputs the speculation value, then the present invention uses the undertaken timing as a setting specification to complete a circuit design. The present invention can improve system efficiency and power of the whole circuit.
