Hi,
I am trying to use the DisplayPort Intel® Stratix 10 FPGA IP Design Example on a Stratix 10 SX device. The design example has a NIOS processor controlling the different Avalon-mm slaves. I have no need for a separate NIOS processor when I have an on board ARM HPS that can do the same thing. I have removed the NIOS processor from the example QSYS project and want to connect the ARM to the Avalon-mm bus in its place.
The issue I am running into is that I cannot figure out how to export the common Avalon-mm bus from the example design as a unified bus. The only option seems to be to export each slave's bus separately. Is there a way to join the buses together and only export a single Avalon-mm bus?

You shouldn't need to export anything. Connect the H2F bridge (master) to all the FPGA slaves you need to control. You can do this by clicking the appropriate dots in the Connections panel or by right-clicking the master interface, going to the Connections submenu, and selecting the slave interfaces to connect to.
Or are you saying you need to connect to parts of your design outside of the Platform Designer system?

So you want to create a hierarchical system design. You can make all the connections in Platform Designer without having to make them in your Quartus project by adding the DisplayPort system as a component. The other .qsys should appear in the IP Catalog.
If you don't want to do this, like you say, add a pipeline bridge to the .qsys file with the ARM processor. Connect the H2F bridge to the slave side and export the master side. That way, if there are any FPGA slaves in the ARM system, you can connect to them as well as export to connect to the other system.

feel free to try out sstrell's suggestion.
Basically the idea is to remove NIOS II connection and convert whole Display Port IP example design as a new custom component in platform designer where you can then hook up to HPS processor.
Thanks.
