Abstract
Systems and methods for avoiding retraining a communication bus after a link failure are disclosed. In particular, in a communication bus that retrains a main band on failure of a sideband, aspects of the present disclosure contemplate using a redundant sideband to keep the bus active and avoid retraining the main band while the failed sideband is recovered. While particularly useful for a Universal Chiplet Interconnect express (UCIe) bus, aspects of the present disclosure may be applicable to other buses with similar sideband arrangements. By avoiding retraining the main band, communication between chiplets is not interrupted, thereby reducing latency for communication between chiplets and improving the user experience.
