Connecting Unconnected Clocks

Information about the clocks in the system appears in the Connections, Name,
Description

, and Clock columns.

Connect all clocks designated as unconnected in the Clock column. Click unconnected
in the Clock column to assign the clock to clk_0.

This instruction does not affect the rapidio_0.clk port, which you exported
previously. This port is designated exported in the Clock column.

You must ensure that you also connect the calibration clock (cal_blk_clk) to a clock
with the appropriate frequency range 10–125 MHz. In this example, the default
external clock, clk_0, is in this range.

Connecting System Components

In Qsys, clicking and hovering the mouse over the Connections column displays the
potential connection points between components, represented as dots connecting
wires. A filled dot shows that a connection is made; an open dot shows a potential
connection point that is not currently connected. Clicking a dot toggles the connection
status. To complete this design, create the connections listed in

Table 8–6
