How works resistor-stuffing option in Cyclone V gt board between SDI Channel and HSM port A, and how change this interfaces?

Hi,

As I understand it, you have some inquiries related to the CV GT devkit. To ensure we are on the same page, just would like to check with you on the following:

1. What is the specific CVGT devkit that you are using?
2. Would you mind to further elaborate on the "resistor-stuffing" that you are referring to? Is it some option mentioned in the user guide?
3. Are you trying to perform some modification to the devkit?

Please let me know if there is any concern. Thank you.
