In this paper. we developed a delay test architecture and test procedure for clocked 5-bit asynchronous counter circuit based on boundary scan architecture. To develope, we analyze the problems of conventional method on delay test for clocked sequential circuit in boundary scan architecture. This paper discusses several problems of delay test on boundary scan architecture for clocked sequential circuit. Conventional test method has some problems of improper capture timing, of same pattern insertion, of increase of test time. We suggest a delay test architecture and test procedure, is based on a clock count-generation technique to generate continuous clocks for clocked input of CUT. The simulation results or 5-bit counter shows the accurate operation and effectiveness of the proposed delay test architecture and procedure.
