It rst encodes a target model into a predicate logic formula in the domain of mathematical arithmetic and bit vectors. We explore how to encode various Simulink blocks exactly. Then, the method veries a given invariance property using the k -induction-based algorithm that extracts a subsystem ...
而Specification 的部分其实有很多重要方向,除了 SAT/SMT solver 涉及到的 logic-based 的验证,还有 type-based (e.g., dependent/refinement/linear types) 的繁复的类型系统们,亦或者包含万物的 Abstract Interpretation。 本文的重点会放在 logic-based 的形式化验证上。

In this paper, we present Pono, an SMT-based model checking tool, with the goal of providing an open research platform for advancing these efforts. Pono is designed with three use cases in mind: 1) push-button verification; 2) expert verification; and 3) model checker development. For 1,...
Computer Science - Logic in Computer Scienceion (in its various forms) is a powerful established technique in model-checking; still, when unbounded data-structures are concerned, it cannot always cope with divergence phenomena in a satisfactory way. Acceleration is an approach which is widely used...
We describe and evaluate three approaches to model check multi-threaded software with shared variables and locks using bounded model checking based on Satisfiability Modulo Theories (SMT) and our modelling of the synchronization primitives of the Pthread library. In the lazy approach, we generate all...
Pono: A Flexible and Extensible SMT-Based Model Checker Pono is a performant, adaptable, and extensible SMT-based model checker implemented in C++. It leverages Smt-Switch, a generic C++ API for SMT solving. Pono was developed as the next generation of CoSA and thus was originally named cosa...

problem from biology – we used it to analyze and synthesize correct executions from scenario-based requirements. (在新选项卡中打开)
the path space using Boolean formulas and verifies the path bycombining abstract interpretation and symbolic execution. The study has conducted experiments based on the F-Softprogram verification platform and SMT solver Z3, and results show that this method performs well based onprecision and effect....
