Thanks Daixiwen,

Ok. Here is I'm trying to do. I try to use mux/demux in between sgdma 1:3 and 3:1 to see the result from output.

sgdma (mm_to_st) -> channel_adpater_A -> demultiplexer -> A (my_module) -> multiplexer ->channel_adapter_B -> sgdma (st_to_mm)

When I run Nios IDE, I could see the result just 1 input (first one) and 1 output. If I assign to the second input, I get 0 result coming out.

Do I need to modify demux module to make it works.
