2.1.1.1. Occasional equalization timeout or PCIe link training failure to achieve expected link speed during speed change, hot reset, and link disable

Description

In the GTS AXI Streaming IP for PCIe* , when you perform a speed change (at Gen4 and Gen3), hot reset, or link disable, in the worst case scenario, an equalization timeout or PCIe* link training failure could occur, preventing the link from achieving the expected speed.

Workaround

Altera recommends verifying the PCIe* link speed after a speed change, hot reset, or link disable procedure. If the PCIe* link speed does not meet expectations, repeat the speed change, hot reset, or link disable procedure to allow the link to recover at the desired speed.
