JESD204C IP with shared PHY

For JESD204C IP, I would like to use TX 8 lanes and RX 4 lanes. Can I instantiate two IPs, one with TX-only (Both Base and PHY) and the other one is RX-only (also Both Base and PHY) and then both IPs...

Hi,

As I understand it, you have some inquiries related to the simplex merging of the JESD204C IP. As I search through the user guide, I am unable to locate any specific info on this. Based on the understanding from JESD204B IP, ideally you should be able to perform simplex merging. However, simplex merging is allowed when both of the simplex instances are of same number of lanes ie TX 4 lanes and RX 4 lanes.

It is also recommended for you to create simple test design in Quartus and run through Fitter compilation to check against internal placement rules.

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


Best regards,
Chee Pin
