As electronic equipment becomes more sophisticated and complex, ATS has gradually exposed the problem of poor versatility. The industry has produced signal-oriented tests and proposed relevant standards to achieve generalization. This method is relatively mature in terms of signal and virtual resource description, but in practice, it needs to complete the virtual-real mapping and other tasks. In response to this problem, a signal-oriented ATS runtime system solution is proposed. Based on ATML standards, a runtime system with initialization channels, signal capability matching, path selection and processing functions is designed to complete the virtual and real mapping from virtual resources to physical instruments. The program is simulated and verified, and the matching results and channel output are in line with expectations. For the development and use of ATS, it is of great significance in reducing special equipment, achieving generalization, and ease of development and maintenance.
