PCIe HIP clocking regression on Stratix 10 MX in Quartus Prime Pro 22.2
Hi,
Thank you for reaching out.
Just to let you know that Intel has received your support request and I am assigned to work on it.
- Can I know which user guide that you are referring on building the IP core from scratch ?
- Can I know which design example of H-tile PCie IP that you are doing ? for example AVMM, AVST or DMA ?
- Is it possible for you to share the design file here so that we can take a look on it ?
Regards,

- I wasn't referencing a user guide, I just deleted the core and created a new one from the IP library, configuring the appropriate settings in the parameter editor. Originally, the core was created via TCL, which was exported from the parameter editor in a previous version of Quartus. I recreated it manually to rule out any issues in the exported TCL.
- It's the AVST core
- I suspect that the issue will appear in the AVST example design. But, I just did some quick testing, and it's also a problem on the 8 lane, 256 bit configuration of the same core, and that design is available here: https://github.com/corundum/corundum/tree/master/fpga/mqnic/S10MX_DK/fpga_10g
Edit: Actually, this design is simpler, and exhibits the same problem: https://github.com/alexforencich/verilog-pcie/tree/master/example/S10MX_DK/fpga

Hi Alex,
Did you try out either H-Tile AVMM/DMA example release by Intel ?
Is it behave the same? Just want to ensure it only happen in AVST or all PCIe related example in 22.2Looking forward to hear back from you.

I have not tested any of the other cores, as my design uses the AVST version with a custom DMA engine. Have you been able to replicate the issue in the example designs that Quartus can generate for the PCIe IP cores?

Hi Alex,
Apologize for the late reply, I had some problems in navigating your design in Github link provided.
Is it possible for you to attach your .qar file here ?
Looking forward to hear back from you soon.Regards,
