The recommended configuration method of the ug_ethernet ip core is not available?

hi

We are using arria 10 to achieve Gigabit Ethernet transmission.Using ug_ethernet provided by altera as a configuration reference.After configuring the mac registers according to the ug_ethernet instructions, we simulate the ip core.But the simulation did not pass.

Next we use the example design generated by altera to simulate the ip core,the simulation passed.

We carefully compared the reference design with our design, only the configuration part is different.So can you give us some advice?

The first picture is the generated example design, the second picture is our configuration, and the third picture is the basis for the configuration of the second picture.
