Honored ContributorGeorge,
from what I understand, Nios II does not require any initialization clocks before releasing reset_n. Assuming your clock is stable, you can connect your reset_n pin to reset Nios. Altera uses the reset_counter to wait until the PLL stabalizes. Personally, I use the PLL_LOCKED signal, and logically OR it with the reset_n input pin (if either is low, then reset Nios). I use an AND symbol to accomplish this. (since we are OR'ing zeros) Hope this helps, -Terry
