Model Checking for a First-Order Temporal Logic Using Multiway Decision Graphs (MDGs)
Ying Xu · The Computer Journal · 2004
We study model checking for a first-order linear-time temporal logic. We present the computation model: abstract description of state machines (ASMs), in which data and data operations are described using abstract sort and uninterpreted function symbols. ASMs are suitable for describing Register Transfer level designs. We define a first-order linear-time temporal logic called LMDG which supports the abstract data representations. Both safety and liveness properties can be expressed in LMDG, however, only universal path quantification is possible. Fairness constraints can also be imposed. The property checking algorithms are based on implicit state enumeration of an ASM and implemented using Multiway Decision Graphs.
