I am creating a block design and use the AXI Interconnect (2.1) as the local bus network. My custom blocks require the AxUSER sideband signals. But when I create the interconnect, the AxUSER signals are not routed!
How can I get the AXI Interconnect to use the ARUSER and AWUSER sideband signals?
As soon as an interface port has a different data width than the AXI Crossbar, AxUSER is ignored. In my example, I have ports that are 64-bits and others that are 32-bit. Depending on the width of the AXI Crossbar, either the 32-bit or the 64-bit ports use AxUSER, but not both!
It looks like the AXI Data Width Converter does not support user sideband signals! Is this a bug or a feature?
