Why does my Stratix® V Hard IP for PCI Express in Gen3 configuration fail to link up to L0 after toggling pin PERST in simulation?

Environment

    PCI Express
    Simulation
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

When simulating Stratix® V and Arria® V GZ Hard IP for PCI Express® as an Endpoint, the PCIe Hard IP can become stuck at Speed. Recovery if the Hard IP is reset after linking up to Gen3 L0. This is a known issue in the simulation model and has no impact on hardware.

Resolution

The issue will be fixed in a future Quartus® II software release.
