Avalon-ST Splitter in VIP cause issues

Honored Contributor II

hello, I did a design with 4 TPG and a mixer (witout alpha) but in reality I will have only one source with 4 differents functions, so I put the Avalon-ST Splitter to have only one TPG and the mixer. Since that moment, the status bit of the mixer is constantly to 0 whereas before it was to 1. I have slightly modify the splitter to remove the "empty" wires because the VIP function don't support it. Any idea ? I use quartus 13.1 with Qsys and a nios II to configure the VIP functions

I solve the problem by building my own Avalon-St Splitter, because the default IP uses a basic "and" between ready signals but the mixer asks data one channel by one channel.
