IVOIRE Workshop 2022

Historically, formal methods and supported environments have focused more on only one-half of the quality-assurance process: verification (are we building the software right?). The other half, validation (are we building the right software?) has been given much less attention, i.e., we have fewer automated/push-button tools available for validation, unlike verification.

The IVOIRE project focuses on developing an enhanced formal paradigm based on an extension of the refinement framework that includes a comprehensive validation process and toolchain to perform validation obligations. The main goal of this workshop is to provide a platform for formal methods practitioners, researchers, and academics to discuss various issues associated with validation for formal methods, including but not limited to:

• Validation obligations or other systematic approaches to validation
• Relation between refinement and validation, and the interplay between verification and validation
• Environments and tools to manage the validation process
• Evaluations, benchmarkings, case studies, etc.

The IVOIRE workshop will be co-located with iFM 2022 in Lugano, Switzerland, taking place on 7 June 2022 (the day before the main conference). The workshop is currently planned to take place physically, like the conference itself.
