Design and Implementation of Function Oriented Test Equipment Driver

As some instrument drivers do not meet the existing standards in a variety of customized test equipment, which reduces the test software development efficiency and quality, a design and implementation method of function oriented test equipment driver is proposed. A set of functional items separated from the hardware environment is obtained and a standardized device driver interface is established via the analysis of the functions of the specific type of test equipment. The control of the hardware instrument is encapsulated in the driver component and the function realization of the actual test equipment is described. The test equipment driver provides a unified development and operation basis for the upper software enabling the test program development for these virtualized functional interfaces to avoid the impact of hardware differences on business logic. The application shows that this method improves the portability and development quality of test program, especially for the test software development of various series with non-standard driver.
