| This dissertation introduces the research and development of the test platform base on a suit of software. Four kinds of basic methods of embedded software simulation platform, which are full digital simulation, semi-practicality open-loop simulation, semi-practicality closed-loop simulation and practicality simulation, are introduced firstly and their advantages and disadvantages are analyzed in this dissertation. According to the present status of testing simulation platform inside/outside China and future development and combined of the testing station's resources. RTX is chosen to be the basic platform to set up two different testing simulation platforms.Peripheral interface of Tested system, demand of the simulation equipment and software and hardware architecture are introduced in this dissertation. Software is include the test case management software, and the middle layer software which is running on Real-time operating environment, and Low-level driver interface. The detailed software design and implementation and effect in Fig are given in this dissertation, too.The first set and second set of platform design are different from the hardware design. The first set is built up a test platform board using multiple cards, which has its own inherent weaknesses. Reusable methodology as a guidance, Chapter V of this dissertation design a high reusability of the program to make up the deficiency based on the traditional hardware design. It is the second program. At the end of the article shows the flag of research program with higher reusability. |
