- 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 22.2
Looking 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,

The problem is not reproducible in the PCIe AVST example design?
