Does PCIe HD IP include the PHY IP Core? How to pin assignment for differential?

Hi all, 

 

I have one starter Kit of Arria V. And I want to realize one application with <Avalon-MM Arria V hard HD IP for PCIe>. 

 

My 2 questions: 

 

1. Does <Avalon-MM Arria V hard HD IP for PCIe> include the PHY IP Core?  

Need I add the additional PHY IP Core for <Avalon-MM Arria V hard HD IP for PCIe>? 

 

2. In the top-level entity of PHY IP Core of PCIe, which signals are for differential couples? How should I do pin-assignment for the differential? 

I cannot find the pair of +/- signals in the interface PHY IP Core of PCIe. It is confusion. 

 

I wait your professional answer.  

Thanks in advance.

Check the development kit user guide for pin details or design example for more information. 

Refer page No 37.

Anand Raj Shankar,  

 

Thanks a lot.  

 

And I've also found one example about Avalon-MM Arria V Hard IP for PCI Express on Arria V GX Starter Kit. The link is following:

It will be helpful for my design. Thanks again. 

 

Best regards
