This correspondence presents a test generation methodology for VLSI circuits described at the functional level. A VLSI circuit is modeled as a network of functional modules such as registers, adders, RAM's, and MUX's. The functions of the individual modules are described using binary decision diagrams. A functional fault model is developed independent of the implementation details of the circuit. A generalized D algorithm is proposed for generating tests to detect functional as well as gate-level faults. Algorithms which perform fault excitation, implication, D propagation, and line justification on the functional modules are also described.
