Trade-Offs in Test Data Compression and Deterministic X-Masking of Responses

While a large body of work on output unknown (X) tolerance exists, to the best of the authors' knowledge, no study is provided in the literature which explores the trade-off between X density and compression of circuit stimuli without reducing fault coverage. To this end, we introduce an architectural and algorithmic framework through which we explore this trade-off, the findings of which we discuss in the experimental results section.
