Videostrem synchronisation

--- Quote Start ---

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!
