Introduction
PCI Express® (PCIe) announced its fourth generation (PCIe 4.0 standard) in 2017. With PCIe Gen 3 the speed of operation was 8 GT/s (giga transfers per second) and error rate is manageable (10-12) but with doubling the frequency with each successive generation performance degradation becomes more pronounced due to variety of reasons like losses in the channels due to different components, reflections in the channel, jitter and cross talk between lanes in a multi-lane system and other parameters varying with process, voltage and temperature (PVT). Solving this problem is another challenge for the designers but the prior issue is to identify them in the live system as they occur since there was no standard approach to identify or
