Functional constraints are an integral part of the VLSI design methodology. Pseudofunctional scan ATPG and untestable fault identification are two areas in test where functional constraints are widely used. The number and complexity of these constraints for large designs become a limiting factor in their successful usage. In this paper we define a constraint minimization problem and present a powerful framework to simplify such constraints. The feasibility and effectiveness of this approach is demonstrated by using untestability analysis of large industrial benchmarks as a case study.
