Why does "fixedclk_locked" signal keep low when "Enable Configuration via the PCIe link" parameter in MegaWizard window of PCIe is enabled?

Description

The "Configuration via the PCIe® Link (CvP)" feature is not available in Quartus® II version 11.1 yet.  If you turn on the option in PCIe MegaWizard™ window for Stratix® V, incomplete RTLs are generated and it causes "fixedclk_locked" signal to be tied low.

To prevent this issue, you must turn off "Enable Configuration via the PCIe Link" parameter in PCIe MegaWizard window. This issue will be fixed in the future release.
