Design of High Confidence Embedded Software Hardware-in-Loop Simulation Test Platform Based on Hierarchical Model

The interactive environment of high confidence embedded software in the field of aerospace and weaponry is complex, with many kinds of interfaces and strong real-time performance. t is a hot research topic how to build its simulation test environment nowadays. In order to solve the problems of low performance and inconvenient interface extension of traditional Hardware-in-loop simulation test platform, this paper uses "hierarchical" + "distributed" design concept to design a Hardware-in-loop simulation test platform based on hierarchical model. The platform uses a distributed architecture, which decomposes tasks such as test task scheduling and incentive data generation into a test controller and adopts a field protocol library to support various bus interface simulations and extensions. The platform is applied to the test of a measurement and control system, and real-time assessment is also carried out, the application and real-time assessment results show that the platform has good versatility, high test efficiency, and its real-time performance in in the level of 100μs
