Thank you help me again.
Does you just change the Pins generated by IP , without the IP inside.
I have seen the sch(\niosII\documents\nios_cyclone_1c20),which have two
IDT71V416.So I wonder whether the IP work if I change the Pins (SOPC generate as you show)or I don't connect the IDT71V416 properly as the example show.
I thought the IP have its specific connection rules outside and it won't work if hardware connection goes wrong or not properly.
Thanks again.
Tommy.
