State Relaxation Based Subsequence Removal for Fast Static Compaction in Sequential Circuits
We extend the subsequence removal technique to provide signi cantly higher static compaction for sequential circuits. We show that state relaxation techniques can be used to ident...

Generation of Test Patterns for Differential Diagnosis of Digital Circuits
In a faulty digital circuit, many (single) faulty gates may explain the observed findings. In this paper we are mostly concerned, not in obtaining alternative diagnoses, but rathe...

Vertex Splitting in Dags and Applications to Partial Scan Designs and Lossy Circuits
Directed acyclic graphs (dags) are often used to model circuits. Path lengths in such dags represent circuit delays. In the vertex splitting problem, the objective is to determine...

Cost-free scan: a low-overhead scan path design
Conventional scan design imposes considerable area and delay overhead by using larger scan ip- ops and additional scan wires without utilizing the functionality of the combinatio...
