MUltiple Avalon Buses in a single FPGA

Hi, Is there a way to have two avalon buses on a single FPGA. I understand that there is avalon interconnection fabic and there can be multiple masters on the bus with multiple slave units with sl...

Thanks!

How can we do this? Assuming that i have multiple Avalon masters and multiple slaves, i understand that, all these masters & slaves are connected on a common avalon bus. If iam going with a point-to-point communication b'n masters & slaves, can the configuration mentioned below is possible?

Avalon bus 1 -- datawidth(32) Address_bus1 - Master 1 -- Slave1

Avalon bus 2 -- datawidth(128) Address_bus2- Master 2 -- Slave2

Avalon bus 3 -- datawidth(16) Address_bus3- Master 3 -- Slave3

There is no mention of multiple avalon busses in the avalon specification document. hopefully there can be multiple data buses on the same avalon switch fabric, but not the bus as whole {i mean address, data and control planes}.

Correct me if i am wrong.
