Abstract
An integrated circuit (IC) device includes a plurality of chiplets including a first device and a second device. A die-to-die (D2D) interconnect link connects between the first device and the second device. A link training and status state machine (LTSSM) of the IC device is configured to operate the degraded D2D interconnect link in a resilient link mode to provide a plurality of enabled lanes and a plurality of disabled lanes. The LTSSM detects a faulty lane among the plurality of enabled lanes, and replaces the faulty lane using a functional lane from the plurality of disabled lanes to maintain the degraded D2D interconnect link.
