Abstract: Against the background of the fast development of IC design and manufacturing, the continuously improvement of the IC's scale and level has promoted the development of test technology.The accuracy of AC parameters has become an important factor affecting the performance of ICs.The paper oversees the basic concepts and principles of AC parametric testing, and discusses the method of AC parametric test.The specific method, flow and test program of AC parameter test based on TR6836 test system is presented. Using the system, the 74HC04 is taken as an example to compare and analyze the two test methods of AC parameters: search method and function verification method.
