ThEodorE: a Trace Checker for CPS Properties

Abstract

ThEodorE is a trace checker for Cyber-Physical systems (CPS). It provides users with (i) a GUI editor for writing CPS requirements; (ii) an automatic procedure to check whether the requirements hold on execution traces of a CPS. ThEodorE enables writing requirements using the Hybrid Logic of Signals (HLS), a novel, logic-based specification language to express CPS requirements. The trace checking procedure of ThEodorE reduces the problem of checking if a requirement holds on an execution trace to a satisfiability problem, which can be solved using off-the-shelf Satisfiability Modulo Theories (SMT) solvers. This artifact paper presents the tool support provided by ThEodorE.

Modular Modeling and Statistical Validation for Grid-Connected FS-MPC-Controlled Matrix Converters

“…Several toolboxes are available for SMC application. Some of them can be directly applied on Matlab/Simulink models, using plugins of the existing software (e.g., Breach [13], S-TaLiRo [14] or Plasma Lab [15]) or by analysing execution traces collected from the simulations (e.g., with ThEodorE [16]). It is also possible to model the system using timed automaton (TA) (i.e., finite state machine) structures, which are applied to define a timed behaviour and analyse realtime systems [17], e.g., using the UPPAAL SMC toolbox [18].…”
