Why is tx_transfer_status asserted after the Low Latency Ethernet 10G MAC IP core is configured to the 1Gbps data rate?

Description

This problem can be observed if the TSE MegaCore 1G PHY is connected with the Low Latency Ethernet 10G MAC Megacore.

The Low Latency Ethernet 10G MAC Megacore does not support TSE 1G PHY connections. This information is available in Low Latency Ethernet 10G MAC User Guide

 

Workaround/Fix

The following configurations are supported:

Use the Multi-Rate Ethernet PHY IP Megacore with Low Latency Ethernet 10G MAC IP core.

or

Use the TSE 1G PHY Megacore with the legacy 10GbE MAC IP core.
