Bit-Precise Conformance Testing of Simulink Model Checkers
Daisuke Ishii, Takashi Tomita, Toshiaki Aoki +1
MATLAB/Simulink provides a practical modeling language and a simulation engine for the development of cyber-physical systems. To ensure the quality of the developed models, there a…
SMT-Based Model Checking of Industrial Simulink Models
Daisuke Ishii, Takashi Tomita, Toshiaki Aoki +3
The development of embedded systems requires formal analysis of models such as those described with MATLAB/Simulink. However, the increasing complexity of industrial models makes a…
Compositional Test Generation of Industrial Synchronous Systems
Daisuke Ishii, Takashi Tomita, Kenji Onishi +1
Synchronous systems provide a basic model of embedded systems and industrial systems are modeled as Simulink diagrams and/or Lustre programs. Although the test generation problem i…
Approximate Translation from Floating-Point to Real-Interval Arithmetic
Daisuke Ishii, Takashi Tomita, Toshiaki Aoki
Floating-point arithmetic (FPA) is a mechanical representation of real arithmetic (RA), where each operation is replaced with a rounded counterpart. Various numerical properties ca…
