New ContributorClocking Avalon slave module outside of the NIOS
Yes, that is what I was picturing. No, there is no difference or advantage in either setup. It's just wires.
If it was my design, I might just include the PLL in the Platform Designer system. That way, I could easily manage the connections to other components I might add to the system, adding an output clock bridge if needed, and making the whole thing more portable.
Super ContributorWhen you say "entering the Nios" or "inside the Nios", I presume you mean "entering the Platform Designer system" and that your box labeled "ATK_Nios" is your Platform Designer system.
First, the clock bridge and clock source components are basically identical. Clock source combines clock with reset. You can use either.
Are you saying that "slow external module" is outside of your Platform Designer system and you are exporting the Nios host (master) interface? If so, you can connect directly to the PLL like the dashed line you have or add an additional clock bridge to your Platform Designer system, exporting the output of that second bridge so the slow clock can be used both inside and outside the system.
I'm not sure if this is what you are looking for.
