摘要
A method to perform diagnostic test generation in sequential circuits by modifying a conventional test generator is presented. The method utilizes circuit netlist modification along with a forced value at a primary input in the modified circuit. Techniques to reduce the computational effort for diagnostic test pattern generation in sequential circuits are also presented. Speed-up of the diagnostic ATPG process is achieved by the identification of states that are impossible to justify with three-valued logic.
