SOPC builder

Hello,

No I've made some code.

I try to insert a video sensor, behaving as a master port for the avalon in my system. Then I use the signals waitrequest and address. I have little questions about that.

When I use the signal address, how can I know what will be those addresses, knowing that in SOPC builder, there are no adresses pre-assigned (as it is a master).

And for the waitrequest, is it automatically sent by the avalon bus each time that the peripheral has to wait?

I hope I was clear and that you won't be annoyed to help me once again.

Thank you.

Romain.
