//Description:   The SpaceWire Routing Switch core(routing matrix).
//               Can be used as a standalone module or connected to the CODEC Core to 
//               form a complete SpaceWire Routing Switch (Router).
//Origin:        SpaceWire Std - Draft-1(Clause 9/10) of ECSS(European Cooperation for Space Standardization),ESTEC,ESA.
