run AN708 on Quartus 21.3

Hi Wchiah,

Thank you very much for the investigation and a clear conclusion. it is very hard to get an ideal solution, but it is very critical to know what is going to happen, especially for a learner. I am not sure I would like to go to Quartus 17. I will spend more time to read ug_a10_pcie_avmm_dma-683425-666332. by the way, beside rely on AN708, is there other example with PCIe and DMA and DDR? the goal is to use PCIe in my application not AN708 itself.

appreciate you time and patience.

David

Hi David,

Is okay, I am happy if can help you. I believe you can be an expert somewhere in the future.

Meanwhile, we can learn together at the moment, I also learn quite a lot from the question you ask right now.

Thanks for actively reply and provide the needed information as well for us to further debug this.

For example related to Arria 10 either PCIe or DMA, you may refer to Intel FPGA design store.

Hope this answer your question,

Wchiah,

If I view this from a different angle, the last update of the PCIe is version 17. which means that Intel gave up the support of the PCIe. I have heard many times that I should use 3rd party PCIe IP. I insisted to trust Intel to its IP. I am kind of understand what my friend's advice now. once it is possible, I should check a 3rd party IP.

Thank you

David

Hi David,

I understand your frustration, but I would emphasize the support until version 17.0 is only specific Arria 10 AN708 design example.

For PCIe IP, the latest version of Quartus do fully support all the way AVST, AVMM to PCIe DMA, and other PCIe design as well.

Besides that, in the latest Agilex device, it support PCIe gen5 as well as some other useful design.

The best I can help at the moment is help to submit an internal ticket to mention that there is a user who request an updated version for Arria 10 AN708 design example that supports latest Quartus version.

Hope this help, let me know if anything else that you feel I can help more.

Wchiah,

Here is a little background of my project, I have an evaluation package from TI data acquisition chip AFE58JD48. the original system is 16 ADCs ( 8 lane of JESD204B, upstream is USB3). I need to use 64 ADCs ( 16 lane of JESD204B), USB3 is not fast enough, so I need to replace the USB3 module to PCIe3. the original design has interface from USB3 to DDR4 control, and I2C. if I have an example like AN708, I can learn how the PCIe interfaced with DDR. that will make it easier for me to integrate the PCIe interface into the system.

besides AN708, any suggestion can make me go forward faster than start from the PCIe user guide will be appreciated.

Thank you for help.

Hi David,

If you have Stratix 10 , you can try to look at

• https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-guidance/pcie-support.html
• Gen3x8 Avalon -MM DMA with External DDR3/DDR4 Memory (AN 829)

Other than that, you may check on

• Intel® FPGA Technical Training Catalog, It help me when I was a pioneer in FPGA area.
• https://www.intel.com/content/www/us/en/support/programmable/support-resources/fpga-training/catalog.html?s=Relevancy
• Also there is an Official Intel FPGA youtube channel which explain step to step function
• https://www.youtube.com/c/IntelFPGA

For PCIe and DDR, you may refe to IP support center

• PCIE , https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-guidance/pcie-support.html
• EMIF , https://www.intel.com/content/www/us/en/support/programmable/support-resources/support-centers/emif-support.html

Hi Wchiah

In fact, AN829 is what I am looking for, but the title didn't mention the DDR interface, so I didn't check in content.

I think this time I do find somewhere to start with.

Appreciate your help. have a good weekend

David

Wchiah,

While I ran simulation of the AN829, I got this error message.

# ** Error (suppressible): (vopt-14408) Intel Starter FPGA Edition recommended capacity is 5000 non-OEM instances. There are 9597 non OEM instances. Expect performance to be severely impacted.

I guess this is because the free simulation tools provide by Intel does not support this complicate project, is that right?

how to solve this problem if not pay the professional simulation tools?

Thank you,

David

Hi Wchiah

I start a new struggle journey on AN829 and posted a challenge at a new thread.

AN829 simulation ran but failed - Intel Communities

hope you can have a look and give me some suggestion.

this needs more detailed investigation into the example because I guess the problem is not just on the tool revision level.

we can close this thread and thank you for all your help.

David

Hi David,

This error is issued when the design capacity for the simulator is exceeded.
See page-11 of https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-20352.pdf
'Known Differences Between the Questa-Intel FPGA Edition and ModelSim* - Intel FPGA Edition'

Few suggestions:
1) In Quartus -> Message tab, right click 'Message', select 'Suppress -> Suppress Message / Suppress Messages with Matching ID to suppress the message。

2) I found this KDB, it uses the "suppress" option along with vsim command ( vsim -suppress 10000)
In your case, probably can try 'vsim -suppress 14408' instead of 'suppress = 14408'

Hope this help.

Hi David,

Thanks, With that said I am closing this thread.

If you feel your support experience was less than a 9 or 10,

please allow me to correct it before closing or please let me know the cause so that I may improve your future support experience.

Great to work with you in this issue
