Dezyne and Dezyne-IDE 2.11.0 released

January 07, 2021

We are delighted to announce Dezyne 2.11: The first standalone release of the Dezyne-IDE that includes simulation and visualization similar to 2.9.

Dezyne-IDE introduces an LSP server ('ide lsp' with basic code completion and goto-definition support.

The documentation, which has not been fully updated for 2.11 yet, is available here:

Dezyne is developed on GNU/Linux, and has been demonstrated to work on the Windows Subsystem for Linux. Dezyne 2.10 is being used on native MS Windows. The Dezyne 2.11 additions on top of 2.10 are not fully tested on native MS Windows, however they do work on WSL2. If you would like to help us to finish the porting effort or repair other shortcomings, please email your bug reports to We will evaluate your reports and track them via the Gitlab dezyne-issues project, see our guide to writing helpful bug reports.

What's next?

In the upcoming releases we aim to introduce a complete and correct state diagram, a language pack for C#, ...

[*] Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this:

gpg --verify dezyne-2.11.0-x86_64-linux.tar.gz.sig

If that command fails because you don't have the required public key, then run this command to import it:

gpg --keyserver --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273

and rerun the 'gpg --verify' command.

About Dezyne

In Dezyne, you define components and their interfaces through a familiar and compact C/Java like-language. The Dezyne language is targeted at the logic or event-driven behaviour of an application. The interfaces are the specification and the components are the implementation.

Dezyne automatically verifies semantic correctness of the logic behaviour and proves that the components correctly implement the interfaces. A user can simulate the behaviour to validate whether this is as intended. Diagrams and logical views are generated automatically from the language description. As a final step code can be generated in a number of standard programming languages.

Without having to rely on a process Dezyne automatically highlights problems areas, stimulates communication about these and enforces that components work together.

About Verum is a leading developer of software design tools to create, simulate, mathematically verify and automatically generate code for embedded and cyber-physical systems.

At Verum, we help our customers and partners solve the most challenging software issues of today and tomorrow. We support customers with our product Dezyne, a software engineering toolset that enables engineers to specify, design, validate and formally verify software components for embedded systems combined with consultancy services.
