Hi,

As I understand it, you are observing some Fitter error in your design related to simple Native PHY RX. This seems to be related to the placement rules. To facilitate further debugging, would you mind to help sharing with me a simple test design with only the Native PHY instances which could replicate similar error. This would allow us to focus only on Native PHY and isolate out non-XCVR related logic or module.

It would be great also if you could share with me a high level XCVR placement that you are trying to implement ie where is the RX/TX/duplex XCVR placed in a XCVR bank together with the target data rate so that I could have a better understanding on your placement.

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

Best regards,

Chee Pin

Dear Chee Pin Attached is the native Rx_simplex phy that produces the fitter error. Please have a look at it and tell which steps to take to get rid of this error. Best Regards Guido Galeazzi
