23.2. Trace System Signals

Table 74.  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 functionality 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.
capturen_startofpacket Input capturen port Avalon-ST startofpacket signal. This signal marks the start of an Avalon-ST packet.
capturen_valid Input capturen port Avalon-ST valid signal. The IP core asserts this signal when it produces data.
controln_address Output controln slave port Avalon-MM address bus. This bus specifies a byte address in the Avalon-MM address space.
controln_burstcount Output controln slave port Avalon-MM burstcount signal. This signal specifies the number of transfers in each burst.
controln_byteenable Output controln slave port Avalon-MM byteenable bus.
controln_debugaccess Output controln slave port Avalon-MM debugaccess signal.
controln_read Output controln slave port Avalon-MM read signal. The IP core asserts this signal to indicate read requests from the master to the system interconnect fabric.
controln_readdata Input controln slave port Avalon-MM readdata bus. These input lines carry data for read transfers.
controln_readdatavalid Input controln slave port Avalon-MM readdatavalid signal. The system interconnect fabric asserts this signal when the requested read data has arrived.
controln_write Output controln slave port Avalon-MM write signal. The IP core asserts this signal to indicate write requests from the master to the system interconnect fabric.
controln_writedata Output controln slave port Avalon-MM write signal. The IP core uses these input lines for write transfers.
controln_waitrequest Input controln slave port Avalon-MM waitrequest signal. The system interconnect fabric asserts this signal to cause the master port to wait.
