Processing APL properties to generate verification-ready MDG model
Kamran Hussain, Otmane Aı̈t Mohamed, Sa’ed Abed · 2009
Multiway Decision Graphs (MDGs) are special decision diagrams that subsume Binary Decision Diagrams (BDDs) and extend them by a first-order formulae suitable for model checking of datapath circuits. In this paper we propose a new specification language, Abstract Property Language (APL), for the MDG model-checker. The APL language eradicates the restrictions present in the existing LMDGspecification language and introduces new operators to improve expressiveness. The paper also presents the design of a front-end translator that accepts specification in APL and builds composite MDG model with the specification directly embedded into its MDG-HDL representation. Finally, some experimental results are presented to show the performance of the APL-Tool and the analysis of the generated code executed on benchmark properties.
