Completing the Qsys System
The APPS component interfaces connect to the Endpoint variant interfaces with
matching names. Most of these interfaces are of the Avalon Conduit type, which is a
point-to-point interface type that accommodates individual signals or groups of
signals that do not fit into any of the other Avalon types. You can connect conduit
interfaces to each other inside a Qsys system or export them to make connections to
other modules in the design or to FPGA pins.
f For more information about Avalon interfaces, refer to the Avalon Interface
Specifications.
Follow these steps to export Avalon Conduit interfaces that connect outside the Qsys
system.
1. To export the
npor interface which is a power-on reset pin for the FPGA, click in
the Export column and type
dut_npor which is the name of the exported interface.
Note that the Connections column now shows that the
npor interface is no longer
available for internal connections in Qsys.
2. Export the following interfaces, using the same name in the Export Column that is
shown in the Name column of Qsys.
■ dut_hip_ctrl
■ dut_refclk
■ dut_hip_serial
■ dut_hip_pipe
■ reconfig_xcvr_clk (This interface is part of the APPS component)
1 You can select Undo Export Interface on the Edit menu if you accidentally
export an interface.
