After checking my design (constrained timequest etc...) and read "user guide SOPC Builder" and "instantiating The Nios II Processor in SOPCBuilder" , I solved my problem.

I think the AVALON pipeline bridges are not necessary for my design.

We need every IO port is connected to the CPU instruction_master in SOPC_builder even if it takes a little more than the resources.

My design work and the Fmax is the same.

thank you for your ideas. :o
