Multiple slave port in SOPC builder

Hi,

I think the problem is the link between the clock interface and the avalon slave interface. Because you can use the same clock for different avalon slave interfaces without problem.

I attach a Quartus II project with a SOPC containing a Nios II, a memory, a custom component with two avalon slave interfaces and one clock, and one component with two clocks and two avalon slave interfaces. And as you can see there is no warning, so you should check the interface tab of the component editor.
