Temporal Reasoning for Procedural Programslar reasoning about procedural programs. We address this issue by defining the semantics of procedural (potentially recursive) programs using . and developing a framework for temporal reasoning around it. This generalization has two benefits. First, this style of reasoning naturally unifies Manna-Pn

Path-Oriented Reachability Verification of a Class of Nonlinear Hybrid Automata Using Convex Programof-the-art tools can only analyze systems with few continuous variables and simple dynamics. Because the reachability problem for general hybrid automata is undecidable, we give a path-oriented reachability analysis procedure for a class of nonlinear hybrid automata called .. Our approach encodes th

An Abstract Domain to Discover Interval Linear Equalitieslts from interval linear algebra. The representation of . is based on a row echelon system of interval linear equalities, which natively allows expressing classical linear relations as well as certain topologically non-convex (even unconnected or non-closed) properties. The row echelon form limits t

Checking Bounded Reachability in Asynchronous Systems by Symbolic Event Tracingdifference logic. The analysis is bounded by fixing a finite set of potential events, each of which may occur at most once in any order. The events are specified using high-level Petri nets. The proposed logic encoding describes the space of possible causal links between events rather than possible

Invariant and Type Inference for Matricesir shapes (also called types), such as upper-triangular, diagonal, etc. To generate loop properties, we first transform a nested loop iterating over a multi-dimensional array into an equivalent collection of unnested loops. Then, we infer quantified loop invariants for each unnested loop using a gen

Deriving Invariants by Algorithmic Learning, Decision Procedures, and Predicate Abstractionopositional formulae. Given invariant approximations derived from pre- and post-conditions, our new technique exploits the flexibility in invariants by a simple randomized mechanism. The proposed technique is able to generate invariants for some Linux device drivers and SPEC2000 benchmarks in our ex
