This paper enables symbolic ternary simulation of systems with large embedded memories. Each memory array is replaced with a behavioral model, where the number of symbolic variable...
In this paper, we report on an application of the validation and veri cation tool kit Uppaal in the design and analysis of a prototype gear controller, carried out in a joint proje...
A state/event model is a concurrent version of Mealy machines used for describing embedded reactive systems. This paper introduces a technique that uses compositionality and depend...
The latest ITU-T standard syntax of Message Sequence Charts (MSCs) 16] o ers several operators to compose MSCs in a hierarchical, iterating, and nondeterministic way. However, curr...
