New component in SOPC builder

you need some kind of interface between sopc and your component, depending an what you want to do

i assume you want to use some kind of cpu like nios to read and or write to your counter, but you haven't added such an interface.

currently you ip has nothing in common with an sopc component except clock and reset.

so there is nothing an external function like a cpu can do with your ip.

maybe you could add a register that holds your enable and this signal can be modified by your cpu via avalon
