10 years ago --- Quote Start --- It's reasonably trivial to export an AXI3 or AXI4 interface from QSys to external HDL by instantiating an AXI Bridge. However AXI4-Lite is not available as a protocol option on this component. It is available (and exportable) on an AXI Slave Agent (or AXI Master Agent) component but I see no way to use these components without building your own Qsys memory mapped interconnect since they expose the Qsys packet interface as Avalon-ST. Is there an obvious way I'm missing to expose an AXI4 Lite interface such that I can connect an AXi4-Lite slave in external HDL?

Otherwise you could just export AXI4 and tie the lines to defaults, setting burst to 0.
