Why does the reset_status signal toggles after pin_perst signal is released in the Stratix® V Avalon® ST Interface for PCIe* IP?

Description

When using the Stratix® V Avalon®-ST Interface for PCIe* IP, you may observe the reset_status signal toggling after pin_perst is released and before ltssmstate signal reaches Polling.Active (0x2). You can safely ignore this behavior and sample reset_status signal until the ltssmstate signal is greater than Polling.Active (0x2).

Workaround/Fix

This information is scheduled to be added in a future release of the Stratix® V Avalon® ST Interface for PCIe* Solution User Guide.
