SatCat5 Change Log

SatCat5 Logo

This log will be updated for each new release, but may not reflect the latest development branch(es).

v1.0.0

  • Initial release of the SatCat5 mixed-media Ethernet switch.
  • Supported FPGA platforms: Lattice iCE40, Xilinx 7-Series
  • Supported Ethernet interfaces: RMII, RGMII, SGMII, SPI, UART
  • Also included: Example designs for the Arty A7 as well as several custom boards, the PiWire adapter software, a Python-based mixed-media-Ethernet chatroom demo, and Jenkins scripts for continuous integration and testing.

v1.1.0

  • Added platform support for the Microsemi Polarfire.
  • New features including improved MAC-address lookup, a virtual port (AXI-mailbox), SPI ports with an output clock, and improved build scripting.

v1.2.0

  • Added contribution guidelines, issue templates, and pull-request templates to encourage outside contributions.
  • Added IPv4 router block.
  • New switch management features including traffic counters and per-port promiscuous-mode.
  • Xilinx platform: Added block-diagram IP-core wrappers for many functional blocks.

1.2.2

  • Fixed AXI4-Lite compliance issues the "port_axi_mailbox" block.

v1.3.0

  • Add support for 802.3D pause-frames.
  • Improved error-handling and error-recovery on SGMII ports.
  • Improved performance of Python/ScaPy interfaces by using L2Socket objects.
  • Update eth_frame_check to block frames where the source MAC is the broadcast address.

v1.3.1

  • Hotfix for inoperable router_config_axi block.

v1.4.0

  • Added diagnostic status flags to the internal Ethernet port definition.
  • Compatibility improvements for SGMII startup handshake.
  • Timing improvements for traffic statistic counters.

v2.0.0

  • Added a large number of auxiliary ConfigBus peripherals, with cross-platform software drivers.
  • Added I2C peripherals and Ethernet-over-I2C ports.
  • Added the "MailMap" port, a higher-performance analogue to original MailBox port.
  • Created an embedded cross-platform C++ driver framework, including a IP and UDP network stack.
  • Replaced all prior MAC-lookup systems with a flexible high-performance TCAM.
  • Replaced various ad-hoc control and configuration functions with "ConfigBus".
  • Reworked switch-core to allow higher maximum throughput, max one full packet per clock.
  • Reworked switch-core to allow rudimentary IGMP snooping.
  • Reworked switch-core to allow traffic prioritization based on EtherType.

v2.0.1

  • Added read/write functions for s8, s16, s32, and s64.
  • Hotfix for UART-16550 driver and Arty-Managed example design.

v2.1.0

  • Added Virtual-LAN support (IEEE 802.1Q) to the Ethernet switch and the software network stack.
  • Defined API for 10-gigabit Ethernet ports.
  • Bug-fixes for eth_preamble_rx and port_inline_status.
