Intro

NetWiz is a stand-alone VHDL library for network protocol packet generation and manipulation. NetWiz offers a stateless and functional API.

NetWiz requires VHDL 2008 and is designed for test bench use only, synthesis is not supported. NetWiz is licensed under the MIT license.

Libraries

Netwiz consists of several libraries. Libraries not related to a specific network protocol are:

• nw_adapt:
  • Configurable settings
• nw_codec:
  • [nw_sl_codec](@ref nw_sl_codec): Stateless generic codec
  • [nw_cobs](@ref nw_cobs): Consistent Overhead Byte Stuffing
  • [nw_bitstuff](@ref nw_bstuff): Bit stuffing
  • [nw_base](@ref nw_base): Base64/32/16 codec
  • [nw_hamming](@ref nw_hamming): Hamming encoding/decoding
• nw_pcap:
  • [nw_pcap](@ref nw_pcap): Read network packets from PCAP/PCAPNG files (produced by Wireshark, tcmpdump et.al.)
• nw_util:
  • [nw_util](@ref nw_util): Functions for data array manipulation
  • [nw_crc](@ref nw_crc): CRC and checksum generation
  • [nw_prbs](@ref nw_prbs): Pseudo-Random Binary Sequence generation.
  • [nw_nrs](@ref nw_nrs): Non-Random Sequence generation

Protocol specific libraries:

• nw_ethernet:
  • [nw_ethernet](@ref nw_ethernet): Create and manipulate Ethernet packets
  • [nw_arp](@ref nw_arp): Create and manipulate ARP packets
• nw_ipv4:
  • [nw_ipv4](@ref nw_ipv4): Create and manipulate IPv4 packets
  • [nw_udp](@ref nw_udpv4): Create and manipulate UDP packets for IPv4
  • [nw_icmp](@ref nw_icmpv4): Create and manipulate ICMPv4 packets
  • [nw_tcp](@ref nw_tcpv4): Create and manipulate TCP packets for IPv4
• nw_ipv6:
  • [nw_ipv6](@ref nw_ipv6): Create and manipulate IPv6 packets
  • [nw_udp](@ref nw_udpv6): Create and manipulate UDP packets for IPv6
  • [nw_icmp](@ref nw_icmpv6): Create and manipulate ICMPv6 packets
  • [nw_tcp](@ref nw_tcpv6): Create and manipulate TCP packets for IPv6
• nw_ptp:
  • [nw_ptpv2](@ref nw_ptp): Create and manipulate IEEE1588v2 packets
• nw_usb:
  • [nw_usb](@ref nw_usb): Create and manipulate USB packets

Additional protocol libraries are expected to be added in the future.
