A four-valued logic and switch-level differences
Mou Hu · 2002
In this paper, the application of a four-valued logic to the switch-level test generation is studied. A switch-level operator fault model is proposed. Switch-level U difference and Z difference of a function to a fault are defined. A method to derive switch-level differences is given. Finally, a new switch-level test generation algorithm for CMOS circuits is presented.>
