SpaceWire Verification IP

The SpaceWire Verification IP is compliant with ECSS-E-ST-50-12C specification and verifies SpaceWire interfaces. It includes an extensive test suite covering most of the possible scenarios. It performs all possible protocol tests in a directed or a highly randomized fashion which adds the possibility to create the widest range of scenarios to verify the DUT effectively.

SpaceWire Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

SpaceWire Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
