using wireshark to examine ethernet frames

pcap extention will be automatically appendedįile_pcap = amiq_eth_pcap_util::init_pcap_file($sformatf('%s.pcap', file_name)) Local integer file_name - the name of the PCAP file.

class for streamming information into a PCAP file. The amiq_eth library contains implementations of the Global Header, Packet Header and Packet Data, as well as a utility class to broadcast a stream of packets in amiq_eth_pcap_util.sv. Start Wireshark, load the HEX dump file, and…yes, it’s as simple as that! Result = $sformatf('%s%06X %02X ', result, i, byte_data) Virtual function string to_wireshark_string() įor(int i = 0 i < byte_data.size() i++) begin returns a string containing the bytes of the packet as required for Wireshark printable bytes of the packet Integer file_txt = $fopen('wireshark_file.txt') A HEX dump file contains the list of bytes of each Ethernet frame and can be created in SystemVerilog like this: // open the HEX dump file Wireshark can read HEX-dumps which are thoroughly described in the Import hex dump chapter. Offline Analysis of Ethernet Packet Streams using a HEX Dump File To generate packets I use the amiq_eth library, a SystemVerilog/SystemC implementation of the IEEE 802.3 Ethernet framing protocol available on AMIQ’s GitHub repository. Installation instructions can be found in the Build and Install chapter. System administrator access rights are required to install Wireshark.

It helps you visualise and analyze hundreds of protocols and you can easily add support for a custom protocol using a dissector.

Wireshark is an open source network protocol analyzer supported by a highly committed community that provides tons of tutorials and documentation. This article shows how to connect the Wireshark network protocol analyzer with a SystemVerilog verification environment in order to visualize Ethernet packet streams, either offline from a HEX dump file or dynamically using live packet capture. Therefore, verification engineers have to inspect and debug Ethernet packet streams generated or monitored by the verification environment. Many protocol stacks in SoCs are based on the IEEE 802.3 Ethernet protocol as the data link layer, while the upper layers can be standard or application specific.
