    Yes, that is what I was picturing. No, there is no difference or advantage in either setup. It's just wires.

Thank you for you responses.

To be sure when you say: "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." Do you mean doing this ?

Would you recommend doing one rather than the other solution (connecting directly the PLL) ?
