4.3.5. TX Avalon® Streaming Filter
The TX Avalon® streaming filter is added in TX adapter to monitor incoming Avalon® streaming TX traffic. When an illegal packet occurs, it raises an error signal. To prevent incorrect behavior downstream, the TX Avalon® streaming filter removes some illegal packets. When illegal patterns occur, it raises the error flag, so that you can be aware of the problem. Some of the illegal traffic patterns are also filtered to prevent downstream problems.
The 4-bit signal tx_avst_bus_err[3:0] is a quick debug indication of protocol error during TX data transmission on user side. This signal is present at top level but is not brought to output pins. Since the top level is clear text, you can connect them when needed.
