A method for enhancing signal integrity in an interface between a source device and at least one destination device includes: analyzing two or more consecutive data patterns intended to be conveyed by the interface to determine whether data transitions corresponding to the data patterns are likely to introduce coupling noise and/or simultaneous switching output (SSO) effects on the interface; generating a modified data pattern for transmission by the interface, the modified data pattern reducing coupling noise and/or SSO effects on the interface compared to an original data pattern intended to be conveyed by the interface; and transmitting the modified data pattern and information regarding a manner in which the original data pattern was modified to the destination device to thereby reduce coupling noise and/or SSO effects on the interface.

Parallel interface pattern modification for addressing signal integrity concerns

A method of designing an integrated circuit, integrated circuits using different drive strengths and a signal integrity monitor are provide herein. In one embodiment, the signal integrity monitor includes: (1) a signal interface configured to receive a signal from a parallel data bus for transmission over a plurality of signal paths and (2) a victim signal identifier configured to dynamically determine a potential victim signal path of the plurality of signal paths.

System and method for decreasing signal integrity noise by using varying drive strengths based on likelihood of signals becoming victims
