How to export Nios2 signals?

Hi, i have designed a custom multiprocessor interconnect (a switch fabric) for my bachelor thesis. One requirement was that it can handle different processor types (load/store architecture). Ma...

To export signals out of QSYS you've to select the row of the respective interface and click the *conduit* column.

Doing that, you've created a conduit.

A conduit is an interface that is routed directly to the outside of the QSYS system.

But if you export the interface of the NIOS (if it's possible in the first place) how do you connect the JTAG-UART?

Maybe you'll export his interfaces too and connect all the conduits to your switch fabric.

At this point you'll have to deal outside of QSYS with the avalon interfaces (NIOS, JTAG-UART) to glue them to your

switch fabric.

Does that fits your needs?
