This brief provides an efficient method to address both logic errors and crosstalk-induced delay variations. In particular, the inherent skew resulting from parity generation is exploited to ensure that no two adjacent wires switch in opposite directions simultaneously, thereby reducing worst-case on-chip capacitive coupling. Data and parity-check bits are mapped to link driver registers, which are triggered by alternating clock phases. The proposed method reduces worst-case link delay by 25… CONTINUE READING
