I'm not an expert in SOPC nor ST designs, as I had developed my own streaming interconnection, which I rather call dataflow interconnection, before looking into Altera's solution. However I looked up the ST- pin connections:

It looks to me that you have instantiated the de-interlacer with a 0 width for the empty signal, and so you must instantiate the splitter wit a 0-width empty signal as well.

Thank you for your reply.

When instantiating the de-interlacer in my SOPC design I don't see any option that would let med deside the width of the empty signal.

When instantiating the splitter, there are several avalon-st interface signals that can be selected/deselected, however the empty signal is not listed.

Is there another way to specify that I wan't to instantiate the splitter with an empty signal of 0 width ?
