Completing the Connections in Qsys
In Qsys, hovering the mouse over the Connections column displays the potential
connection points between components, represented as dots on connecting wires. A
filled dot shows that a connection is made; an open dot shows a potential connection
point. Clicking a dot toggles the connection status. To complete your Qsys system,
follow these steps:
1. To view all the component interfaces, including the clock and interrupt interfaces,
click the filter icon on the left edge of the System Contents tab and in the Filter
menu, select All Interfaces.
Figure 16–2 shows the filter icon.
