thanks again!

I had a dhcp server, and I can run well with the DE4 sample(sopc builder). I just make a project with qsys reference to the DE4 sample and altera ethernet sample.

I want run cpu with high Fmax, 150Mhz. but I can't work first!

so, I think I connect the network correctly and the dhcp server is ok.

maybe somewhere is wrong,I will only debug and modify it with my effort.

If you want to use DHCP you need a DHCP server on your network. Do you have it?

During initial testing you'd better disable DHCP and use a fixed well known IP address.

If you can't ping it, there are a number of possible reasons:

- your pc is not configured with the same subnet as the DE4 board. Check network settings on your pc

- your fpga design is not fully constrained and it possibly has timing problems

- other flaws in fpga design (i.e. pin assignment): did you use a standard sample design or did you build it from scratch?

- you missed something in Nios bsp or application settings
