Agilex E tile - Error(20672): For HSSI E-tile, there is no path between HSSI REFCLK and core.

Hi Shubhangi,

Thank you for reaching out.

Apologize for the delayed response.

Based on the Agilex OPN number, I believe that you are using Intel Devkit DK-SI-AGF014EA (Prod) type.

Have you set the VID settings as below?

6.1. Add SmartVID settings in Intel® Quartus® Prime QSF file

You are required to input above script/code to avoid Quartus from generating an error due to incomplete SmartVID settings.

You may change the scripts listed below in you project QSF file.

Please ensure that there are no other similar settings with different values.

For more information you may refer to below link:

Intel® Agilex™ F-Series Transceiver-SoC Development Kit User Guide - 6.1. Add SmartVID settings in Intel® Quartus® Prime QSF file

Hope this helps solve your issue.

Thank you.

Best Regards,
