Hardware Implementation of Intel JESDIP Core with Agilex 7 and AFe7950EVM

[Vandana_GS]

Hi everyone,

I am trying to configure Intel JESDIP Core with Terasic Agilex SOM Module FPGA: Agilex AGFB014R24B2E2V development kit  and TI's AFE7950EVM. While configuring the board in simplex mode(only transmit) we are getting error as follows in the system console.

Could you please suggest what could be the problem because of which we are getting this error? The reference clock used is 184.32MHz and LMFS=12410 Data rate=7372.8Mbps.

When I am trying with TX-RX example design with same clock and LMFS configuration also I am getting the same error as shown above.

Thank you

Hi,

Thanks for contacting Intel. I'm assigned to support request.

I'll investigate on this case related and get back to you soon once I have any finding.

Meanwhile can I check with you on:

1. Quartus version
2. OPN number
3. Clock is stable? (have you checked it with CRO), since you are having issue with both example design as well as custom one.
4. Check for any warnings while IP generation and timing issues.
5. Have you checked with preset example design (since you mentioned that you have generated example design with your configurations).

Thanks for your patience.

Best regards,

Hi,

Thank you for the reply.

1.The Quartus version we are using is 24.1.

2.OPN number is AGFB014R24B2E2V.

3. Please explain from which point on the FPGA  can we check the clock stability. 

4. There were no warnings while IP generation and timing issues.

5. I was able to generate the simulation with help of preset design with LMF=122 and Data rate=6144Mbps . But the same cannot be implemented in hardware as there is design restriction in the AFE7950 for data rate 6144Mbps. That is the reason to work with the  reference clock used is 184.32MHz and LMFS=12410 Data rate=7372.8Mbps.

Please assist us in resolving the issues.

Thanks and regards,

Hi, please reply to the query

Hi,

It seems you have no proper clock in your design.

You can check using BTS(Board test system)

Go to your Development Kit user guide, check under Board Test System section (example: 4.3. Control On-board Clock through Clock Controller GUI).

Kindly download installer package for your device from intel (Agilex™ 7 FPGA I-Series Development Kit (2x R-Tile and 1x F-Tile)) from there check DV kit user guide-> Board Test System section.

You need to align the proper clock to the pin you have selected in design (Use schematic from the package to check for clock pins)
