Synthesizable VHDL core implementing the SpaceWire Codec (including testbenches).
Overview
The SpaceWire-b (SpW-b) CODEC is a high speed serial transmitter/receiver compliant with the SpaceWire standard.
The SpaceWire CODEC is responsible for making a connection with the SpaceWire interface at the other end of a link and managing the flow of N-char across the link.

Sample user system utilizing the SpaceWire-b CODEC
The interface transmits and receives SpaceWire characters which can be link characters (L-Char) or normal characters (N-char).
L-Chars are characters that are used to manage the flow of N-char across a link (NULL & FCT).
N-chars are the characters that are used to pass information across the link (N-char characters, EOP, EEP and TIMECODEs).

Current Release
version 2.3, 01-Apr-2009
For a history of bug reports and fixes, modifications, upgrades, etc, please refer to the SpaceWire-b IP Core Release Notes.
An application note describing the complete design flow for implementating the SpaceWire-b CODEC in an Actel RTAX FPGA, along with the complete design database, is also available to licensed users upon request.
Special licensing restrictions
ESA can grant licenses for the use of the SpaceWire-b IP core only for activities funded by the Agency (ESA projects).
The IP core also incorporates the IEEE 1355 High Performance Serial Bus Std (Data/Strobe interface) patented by STMicroelectronics, so an appropriate STMicroelectronics patent notice must be included in the licenses and the final products.

Licensing
ESA IP cores can generally be licensed to be usedin the frame of ESA contracts, orfor privately-funded activities.Depending on the particular IP core needed, restrictions on its usage might be present, so please refer to the web pages dedicated to each individual ESA IP core for more details.In any case, the procedure for requesting and licensing ESA IP cores is the same, and the following conditions apply:Licences can only be granted to companies or institutes that provide ESA with a duly completed IP Request Form.the scope of use of the ESA IP cores is limited to peaceful purposesno warranty or technical support is provided by ESA.
