The VPI Pcap library provides a set of Verilog VPI calls which can be used to capture packets from a Verilog simulation and write them to a pcap format file, which can then be read in to Wireshark or other packet analysis tools.
This library is dependent on the “pcap” library used by tcpdump and wireshark for their packet storage and description. You can install this by doing:
yum install libpcap-devel
