In our setup (avery bfm with other qsys design (includes hard ips) for the very first pcie config read no response from pcie_ptile hard IP. 

 

How can we identify whether ptile is timed out or not.

If the (config transaction) bus number is not matching with ptile bus number, ptile will simply timed out or it will send any response. Below is the message fetched: For reference please go through the tracker file.

Hi,

 

Is this problem happen during enumeration? Are you using the example design in Appendix D (page 211)?
