2.1.1.6. Intermittent Equalization Timeout or Speed Degrade during Link Disable, Hot Reset, and Speed Change

Description

In the F-tile Intel® FPGA IP for PCIe* , when you perform link disable, hot reset, or speed change (at Gen 4 and Gen 3), there is a negligible chance of running into the equalization timeout or speed degradation.

If equalization timeout occurs, the link is expected to re-attempt the transmitter equalization or retrain the link to achieve link up at desired speed by default. If the link settles at the degraded link speed, an additional speed change request is required for the link to recover at the desired speed.
