1 X1 can be built
2 link up with x1 on gt0
3 if lane reversal is enabled, link up to x1 on gen1, if not , link is down

Thank you for your answer.
Do conditions 2 and 3 automatically link-up again?
In the simulation, how long can pci_exp_txp / n  be 0-clamped to reproduce?
In the simulation, I can confirm the link down when pci_exp_txp / n [1: 0] is clamped to 0 about 100us.
