Abstract

SpaceWire is a high-speed, full-duplex serial bus standard which is applied in aerospace, so its functions require high accuracy. The traditional methods of verification, such as simulation and test, are not complete. In order to prove the design of the SpaceWire faithfully implemented the SpaceWire protocol’s specification, we presented our experience on the model checking of SpaceWire data flow control using the Cadence SMV tool. It overcomes the incompleteness of traditional verification. And by injecting the errors to ensure the accuracy of the artificial extraction properties and completeness, comparison tests show that the method can effectively ensure the functional coverage, improve reliability of the verification.
