High levels of safety, security and also privacy standards require the use of formal methods to specify and develop compliant software (sub)systems. Any standard comes with an assessment process, which requires a complete documentation of the application to ease the justification of design choices and the review of code and proofs.

Ideally, an F-IDE dedicated to such developments should comply with several requirements. The first one is to associate a logical theory with a programming language, in a way that facilitates the tightly coupled handling of specification properties and program constructs. The second is to offer a language/environment simple enough to be usable by most developers, even if they are not fully acquainted with higher-order logics or set theory, in particular by making development of proofs as easy as possible. The third is to offer automated management of application documentation. It may also be expected that developments done with such an F-IDE are reusable and modular. Tools for testing and static analysis may be embedded within F-IDEs to support the assessment process.


The workshop is open to contributions on all aspects of a system development process, including specification, design, implementation, analysis and documentation. It welcomes the presentation of tools, methods, techniques and experiments. Topics of interest include, but are not limited to, the following:

  • F-IDE building: design and integration of languages, development of user-friendly front-ends
  • How to make high-level logical and programming concepts palatable to industrial developers
  • Integration of Object-Oriented and modularity features
  • Integration of static analyzers
  • Integration of automatic proof tools, theorem provers and testing tools
  • Documentation tools
  • Impact of tools on certification
  • Experience reports on developing F-IDEs
  • Experience reports on using F-IDEs
  • Experience reports on formal methods-based assessments in industrial applications


Prof. Jan Friso Groote

An overview of the mCRL2 modelling and verification toolset

Jan Friso Groote  is a Full Professor and Chair of Formal Systems Analysis group in the Department of Mathematics and Computer Science at Eindhoven University of Technology (TU/e), and has been working at ASML part-time. His areas of expertise include Computer systems, architectures, software, algorithms, embedded systems and formal methods. Jan Friso has contributed to  structural operational semantics  and verification technology. He is the founding father of the process modeling language and analysis tool set  mCRL2. This tool set makes it possible to describe the behavior of software with data, time and probabilities, whilst proving properties related to this behavior, expressed in the modal mu-calculus, as well as reducing and visualizing this. His industrial experience shows that improvements to the verification techniques and algorithms, and the usage of software development styles suitable for verification reduce the development time with a factor three increasing the quality with a factor 10. Especially regarding the quality, it can be expected that substantial further improvements are possible, hopefully leading to zero defect software.


Challenges of a point & click mathematical proof builder interface

One of the key features of Edukera is the ergonomic design of the numerical paper which allows students to build a mathematical proof with point and click interactions. This numerical paper has been developed and improved over several years of experiment with students' and teachers' feedback. This session will address the key challenges a formal proof interface may pose:

  • How to present a mathematical proof?
  • Shall a proof assistant mimic the manual process?
  • How to build a proof? Should it be like developing code or should it be with point & click interactions?
  • How to present a theory (set of theorems) and search in it?
  • How to conduct calculations?
  • How to deal with obvious deductive arguments?

This session will show the experiments that have been conducted over the years and their outcomes.

The company

Edukera, created in 2014, has developed an online educational application to teach mathematics that relies on the use of the formal proof assistant Coq (developed by Inria).

Since its commercial launch in 2016, the Edukera application has been used with success in several universities by 8,500 students who have solved over half a million exercises.

Submission Guidelines

We accept both long (15 pages) and short (6 pages) paper submissions. The page limit does not include the bibliography. Submitted papers must present original contributions whose main results and conclusions have not been published or submitted elsewhere. Each submission will be reviewed by at least three members of the Program Committee. We expect that one author of every accepted paper will present their work at the workshop.

Submitted papers must be written in English and follow the EPTCS LaTeX format (http://style.eptcs.org). Authors are invited to submit the following types of contributions:

  • Research papers providing new concepts and results    
  • Experience reports    
  • Position papers and research perspectives    
  • Tool presentations 

Papers should be submitted via EasyChair at F-IDE 2021's workshop page::


Preliminary proceedings will be made available in electronic form at the workshop. Post-proceedings will be published in the Electronic Proceedings in Theoretical Computer Science (EPTCS).
