This paper develops an improved approach for hierarchicalfunctional test generation for complex chips. In orderto deal with the increasing complexity of functional testgeneration, hierarchical approaches have been suggestedwherein functional constraints are extracted for each moduleunder test (MUT) within a design. These constraintsdescribe a simplified ATPG view for the MUT and therebyspeed up the test generation process. This paper developsan improved approach which applies this technique atdeeper levels of hierarchy, so that effective tests can bedeveloped for large designs with complex submodules. Atool called FACTOR (FunctionAl ConsTraint extractOR),which implements this methodology is described in thiswork. Results on the ARM design prove the effectiveness ofFACTOR-ising large designs for test generation and testabilityanalysis.
