This work introduces a notion of refinement into a ‘run to completion’ statechart modelling notation, and uses Event-B’s tool support for theorem proving to leverage its tool support for theorem proving.
Formal methods, including model checking, are rapidly gaining importance, especially in safety-critical domains like aerospace and automotive. Consequently, the systems to be verified are growing more complex and are described in diverse design languages, often expressive and ambiguous. However, model checkers oper...
Proof-Sketch-Guided Formal Model Synthesis (ProGS), an autoformalization method centered on model-based proof sketches, which improves over state-of-the-art agentic formal modeling approaches in syntactic validity, deductive verifiability, and behavioral correctness.
In many industrial systems, control-related information is often opaque, undermining the ability to formally ensure safety, correctness, and performance. Representing such systems as Discrete Event Systems (DES) models enables rigorous analysis, synthesis, and correct-by-construction control, but modeling is typically...
This work proposes an integrated view on the use of LLMs for EDA and establishes an LLM-enabled behavior driven hardware development workflow, introducing and defining Formal Verification Gherkin Scenarios (FV Gherkin Scenarios), unlocking CNL specifications as the foundation for formally verified hardware designs via...
The coroutine has broadly diffused in the practice of concurrent programming in the form of generators and asynchronous functions as well as processes communicating through pipes. We wanted to use coroutines in Python to create single-threaded Unix-style pipelines. Unfortunately, available solutions in Python are cumbe...
Formal methods applied to requirements specification can be categorized into model-based and property-based approaches, each with distinct advantages in formalizing and verifying different aspects of system requirements. This paper provides a retrospective review of Formal Tropos, a pioneering methodology in Requiremen...
