Interfacing ASM with the MDG Tool - Gawanmeh, Tahar, Winter (2003) (Correct)
....exploit the notion of abstract types. This concept provides a simple means for abstraction in order to abstract from in nite data types. This feature can be essential when applying automated veri cation techniques like model checking. 3 Multiway Decision Graphs Multiway Decision Graphs (MDGs) [4] is a relatively new class of decision diagrams which subsumes the traditional ROBDDs (Reduced Order Binary Decision Diagrams) 11] while allowing abstract data sorts and uninterpreted function symbols. MDGs are based on a subset of many sorted rst order logic, with a distinction between abstract ....

In order to verify designs with this tool, we need rst to specify ....

A Tool for Verifying ASM Models Using Multiway Decision Graphs - Gawanmeh, Tahar, Winter (2003) (Correct)
....and tool support recently, this is because of the increasing complexity of digital VLSI systems, and as a result, it is becoming impossible to simulate large designs adequately. In this work we describe an approach to interface Abstract State Machines (ASM) 4] with Multiway Decision Graphs (MDG) [1] to enable tool support for the formal verification of ASM descriptions. ASM is a formal specification method for software and hardware modeling and provides a powerful means of modeling various kinds of systems. An ASM model describes the state space of the system by means of universes or ....

For each of these models, variable order and algebraic specifications [1] are also generated. We developed the interface for behavioral designs in two steps as shown in Figure 1: in the first step a model in Specification Language ASM SL [2] is transformed into a flat, simple transition system, called the Intermediate Language (ASM IL) 5] The second step provides a ....

In both cases, the authors were making use of the data abstraction features of the MDG representation and tool [3].

The verification is based on reachability analysis of the product machine of the implementation and the specification, modeled as networks of Abstract State Machines (ASM) [6]. MDGs are used to encode the output and transition relations of ASMs and the set of reachable abstract states, allowing implicit abstract state enumeration. Using the applications provided by the MDG software package, all verification tasks were achieved fully automatically in a reasonable amount ....

Multiway Decision Graphs (MDGs) have been recently proposed to represent circuits at a more abstract level [6]. MDGs are based on a subset of a many sorted first order logic with abstract sorts and uninterpreted function symbols. They subsume the class of Reduced Ordered Binary Decision Diagrams (ROBDD) 2] In the next section, we will briefly describe MDGs and their verification methods. For more ....
