VII. CONCLUSION Benefiting from the RFM, the test platform can realistically simulate not only the synchronization and CCDL between multichannel, but also various avionics bus. The testing platform can run real-time applications, account the execution time of the realtime task, test redundant management logic, and promptly corrected the software writing BUG and logic BUG. So, the new rapid prototyping test method can improve the software development efficiency and shortens the product development cycles greatly.
