Description
When system software generates a Power Management event, the PCIe core may not respond properly to Power Management sequence. As a result, it may cause system lockup or blue screen.
To workaround the problem, user should hardwire test_in[7] to high.
This issue exists in Quartus® II software v10.0SP1 and earlier versions.
For v10.1, this problem is fixed for Avalon-ST interface. However, if the core is created from SOPC builder (Avalon-MM), you need to set test_in[7]=1 manually to work-around this issue. This problem will be fixed in future software release.
