You will not be able to tie the SOF signals with Nios. This is better done in the top-level HDL file. The SOF signals are exported by the Qsys/SOPCBuilder system.

I have looked for this before, but I can't find the SOF signals, because of this I thought I have to use NIOSII.
In the CVIs, the "Generate Synchronization Output" is set to "yes".
In the CVOs, the "Accept Synchronization Outputs" is enabled.
After set both, I have regenerated the SOPC system. But in my top.bdf I can't see any SOF out- or inputs.
In SOPC.v, I have only the following in and outputs:
module CVI0_dout_arbitrator (
// inputs:
CVI0_dout_data,
CVI0_dout_endofpacket,
CVI0_dout_startofpacket,
CVI0_dout_valid,
Clipper0_din_ready_from_sa,
clk,
reset_n,
// outputs:
CVI0_dout_ready,
CVI0_dout_reset
)
;
Thanks for help!
