The Trace System IP core is a debugging and monitoring component.
The trace system collects data from various monitors, such as the Avalon-ST monitor, and passes it to
System Console software on the attached debugging host. System Console software captures and
visualizes the behavior of the attached system. You can transfer data to the host over one of the following
connections:
• Direct USB connection with a higher bandwidth; for example On-Board USB-Blaster
™ II
• If you select the USB connection to the host, the trace system exposes the
usb_if
interface.
• Export this interface from the Qsys system and connect to the pins on the device that connects to
the On-Board USB-Blaster II.
Note: To manually connect the
usb_if
conduit, use the USB Debug Link component, located in
Verification > Debug & Performance.
• JTAG connection
• If you select the JTAG connection to the host, then the Quartus II software automatically makes the
pin connection during synthesis.
The Trace System IP core transports messages describing the captured events from the trace monitor
components, such as the Frame Reader, to a host computer running the System Console software.

When you instantiate the Trace System IP core, turn on the option to select the number of monitors
required. The trace system exposes a set of interfaces:
capturen
and
controln
. You must connect each
pair of the interfaces to the appropriate trace monitor component.
