Hi Dave,

Thank you for your quick response!

We are indeed using QII 12.1sp1, and the first line of the generated vhd file also indicates it was generated from 12.1:

-- megafunction wizard: %IP Compiler for PCI Express v12.1%

I also double checked the MegaWizard configurations page by page against the copy that worked (and compiled in 11.0), they are the same.

Basically we supplied the same source files and configuration files as far as I can tell, to two different compilation processes (11.0 vs 12.1sp1), both compiled successfully but one image fails to be detected by BIOS.

Is there anything in the hard core that I can use signaltap to check if the it is in working condition? Like checking the link status or something like that?

Thanks,
