Collaborative Simulation Testing with State Behavior Tree

Abstract

Validation method based on simulation is generally used to ensure reliability of the embedded system. Combination of hardware in the loop simulation and full digital simulation to carry out collaborative simulation can use one's strengths to off-set the other's weaknesses, which is the most common means used. In order to resolve challengesfacedin collaborative simula-tion test along with hybrid real-time task scheduling, this paper proposed an optimized method of collaborative simulation test based on state behavior tree, which is composed of hierarchical design strategy of the test scripts, organization model of the states and behaviors in test execution as the state behavior tree struc-ture, test optimization by reusability of test execution results based on state behavior tree and hybrid real-time task scheduling mechanism. Experiments showed that this optimized method can improve test efficiency ofautomatic collaborativesimulation test combining hardware in the loop simulation and full digital simu-lation.
