Agilex DDR4 Interface Debug

Hi Emrah,

"EMIF Toolkit does not support Agilex Family FPGAs but EMIF IP user guide still address this toolkit for JTAG debugging."

Which EMIF Toolkit that you mean here?

"Is there a suggested methodology and/or tool for debugging DDR4 interfaces through JTAG? "

You can debug the EMIF interface with EMIF Debug Toolkit or On Chip Debug Port. The details can be referred to links below:

• https://www.intel.com/content/www/us/en/docs/programmable/683216/22-4-2-6-1/debugging-with-the-external-memory-interface.html
• https://www.intel.com/content/www/us/en/docs/programmable/683216/22-4-2-6-1/emif-on-chip-debug-port.html

"Can we debug HPS DDR4 using the same methodology?"

To debug the HPS EMIF, we will use Fabric EMIF IP with HPS EMIF pin placement. The HPS EMIF is not supported by the debugging tools.

Hi Emrah,

Can you confirm that the EMIF Debug Toolkit has been enabled in the design?

For Agilex, the EMIF debug toolkit is accessed through System Console, not what you are selecting in the screenshot. Open System Console first and you'll then find the option for the toolkit.

Hi Emrah,

Are you still facing the issue at the moment? Any update in this thread?

Hi,

Can you please be more specific with `EMIF Debug Toolkit has been enabled`. ?

External Memory Interfaces Intel Agilex IP has a parameter in Diagnostics Tab.

Disabled : Certainly we dont want this .

Export : EMIF debug interface IP core is not among available IP list in IP Catalog.

I selected Add EMIF Debug Interface and Rerunned the whole flow starting from Generate HDL. When I downloaded the .sof file I could not see any selection in the system console system (Debugger Tools /System Console).

Since the related parameter is under the title Example Design (Diagnostics Tab not Example Design Tab) I generated the example design and will try downloading the resultant sof file .

See this training for details on this:
