We describe a technique to generate critical hazard-free tests for self-timed control circuits built using a macro-module library, in a partial scan based DFT environment. We propose a six-valued algebra to generate these tests which are guaranteed to be critical hazard free under an unbounded delay model. This algebra has been incorporated in a D-algorithm based automatic test pattern generator.
