SpaceWire Verification IP

Truechip's SpaceWire Verification IP provides an effective & efficient way to verify the components interfacing with SpaceWire interface of an ASIC/FPGA or SoC.
 Truechip's SpaceWire VIP is fully compliant with ECSS-E-ST-50-12 C rev 1 specification of SpaceWire. This VIP is a lightweight with an easy plug-and-play interface so that there is no hit on the design time and the simulation time.

Key Benefits
