4. To display the parameters of the APPS component shown in Figure 2–3, click on it
and then select Edit from the right-mouse menu Figure 2–4. illustrates this
component. Note that the values for the following parameters match those set in
the DUT component:
■ Targeted Device Family
■ Lanes
■ Lane Rate
■ Application Clock Rate
■ Port
■ Application interface
■ Tags supported
■ Maximum payload size
■ Number of Functions
1 You can use this Qsys APPS component to test any Endpoint variant with
compatible values for these parameters.
5. To close the APPS component, click the X in the upper right-hand corner of the
parameter editor.
Go to “Simulating the Example Design” on page 2–11 for instructions on system
simulation.
