This paper explores the idea that redundant operations, like type errors, commonly flag correctness errors. We experimentally test this idea by writing and applying four redundanc...
In order to extensively explore design space one has to specify a n a very abstract level. Transforming a specification into a correct implementation is usually an error prone tas...
We give timed automaton models for a class of Programmable Logic Controller (PLC) applications, that are programmed in a simple fragment of the language Instruction Lists as defin...
Although verification and simulation tools are always improving, the results they provide remain hard to analyze and interpret. On one hand, verification sticks to the functional ...

-- This paper presents an efficient method for the timing verification of concurrent systems, modeled as labeled Timed Petri nets. The verification problems we consider require us ...
