This core would be very suitable for application in lab environments,

to add a SpaceWire interface to a custom FPGA design, and for interfacing
 
between existing SpaceWire equipment and a computer.
 
 
 
The project is currently very much in alpha phase. Most importantly,
Future plans:
there is no proper documentation. I WILL PROVIDE DOCUMENTATION SOON.
 
 
 
Short term plan:
 
 * more testing
 
 * documentation
 
 
 
Long term plan:
 
 * add AMBA bus interface
 * add AMBA bus interface
 
 * try to run on Virtex
