Trace System Signals

Table 20-2: Trace System Signals

Signal

Direction

Description

clk_clk

Input

All signals on the trace system are synchronous to this

clock.
Do not insert clock crossing between the monitor and

the trace system components. You must drive the

trace monitors’ clocks from the same source which

drives this signal.

reset_reset

Output

This signal is asserted when the IP core is being reset

by the debugging host. Connect this signal to the reset

inputs on the trace monitors.
Do not reset parts of the system being monitored with

this signal because this will interfere with function‐

ality of the system.

usb_if_clk

Input

Clock provided by On-Board USB-Blaster II.
All

usb_if

signals are synchronous to this clock; the

trace system provides clock crossing internally.

usb_if_reset_n

Input

Reset driven by On-Board USB-Blaster II.

usb_if_full

Output

Host to the target full signal.

usb_if_empty

Output

Target to the host empty signal.

usb_if_wr_n

Input

Write enable to the host to target FIFO.

usb_if_rd_n

Input

Read enable to the target to host FIFO.

usb_if_oe_n

Input

Output enable for data signals.

usb_if_data

Bidirectional Shared data bus.

usb_if_scl

Input

Management interface clock.

usb_if_sda

Input

Management interface data.

capturen_data

Input

capturen

port Avalon-ST

data

bus. This bus enables

the transfer of data out of the IP core.

capturen_endofpacket

Input

capturen

port Avalon-ST

endofpacket

signal. This

signal marks the end of an Avalon-ST packet.

capturen_empty

Input

capturen

port Avalon-ST

empty

signal.

capturen_ready

Output

capturen

port Avalon-ST

ready

signal. The

downstream device asserts this signal when it is able

to receive data.
