Confident Algorithms with Formal Proof Techniques

By: AdaCore
23 June 2020 at 15:26

Sensor fusion software is unique with its combination of firmware-like layers, responsible for reading and validating sensor data, and higher-level algorithmic software, responsible for producing synthesized, actionable data. Because of the criticality of these systems, they require extensive testing and verification to increase confidence that the computed data can be trusted. From a software development point of view, the traditional approach is to rely on the C or C++ programming language, and to offset its inherent safety vulnerabilities by using expensive tooling and human-based processes. In this presentation we will present an alternative approach, through the usage of a different programming language which was designed for safety critical systems and gives developers tools to write safe and secure firmware, as-well-as, robust high-level algorithmic code with the same ecosystem of language and tooling. Topics covered:

- Overview of Ada and SPARK language features for firmware development
- Overview of Ada and SPARK language features for algorithm and high-level software development
- Overview of formal proof and how it differs from traditional static analysis techniques
- Integration with existing C code bases
- Performances considerations
- ISO 26262 considerations and benefits
- Resources for Ada and SPARK in the software community

Product Roadmap 2020 — GNAT Pro

By: AdaCore
27 October 2020 at 13:39

GNAT Pro is a robust and flexible Ada, C and C++ development environment. It comprises a toolchain based on the GNU GCC technology; an Integrated Development Environment (GNAT Studio); a comprehensive toolsuite, including a visual debugger; and a set of libraries, bindings and tools.

GNAT Pro is upgraded annually, and Version 21.0, released earlier this month, adds support for a number of new platforms, including VxWorks 600+ on x86 / ARM / PowerPC; C++ availability on all VxWorks 7 ports; Windows-hosted Linux cross for ARM (PowerPC is also available); and RISC-V 32 on bare metal. Version 21.0 also adds a number of key features, including a more powerful CCG (Common Code Generator), new Libadalang capabilities for Ada code analysis, and support for key features of the Ada 202X standard. All of these upgrades are designed to better support multi-language and safety-critical development as well as security vulnerability resilience.

Check out this video to learn how GNAT Pro’s new platforms, tools and libraries can help kick your workflow up to the next level.

Product Roadmap 2020 — SPARK

By: AdaCore
27 October 2020 at 13:39

SPARK Pro is a language and toolset that allows developers to formally define and automatically verify software requirements to guarantee that a program behaves as intended. You can adopt SPARK either at the beginning of a project, or by progressively integrating it in an existing codebase developed, for example, in Ada, C or C++.

AdaCore’s release of SPARK Pro 21.0 expands its support of Ada language constructs, allowing more programs to be effectively specified and verified, and provides better tool interactions with improved tool messages and guidance.

Check out this video to discover how the latest capabilities in SPARK 21.0 can help you save time and effort while reaping the full benefits of formal program verification.

Product Roadmap 2020 — GNAT Studio

By: AdaCore
27 October 2020 at 13:39

GNAT Studio is a powerful and intuitive IDE that supports the full development workflow, from coding to system integration, testing, debugging, and code analysis. It is particularly well-suited for programmers using Ada, SPARK, C and C++.

This year the interface remains the same on the outside, but we have a new engine behind GNAT Studio: the Ada Language Server (ALS). This new engine is based on Libadalang and isn't compiler-dependent, compared to our previous technology that depended on ALI files generated from a compilation. ALS uses the Microsoft Language Server Protocol (LSP), that defines a standard communication method to connect development tools with local language servers. This common framework makes it easy for IDEs to support more languages, and it makes it possible for language-specific code to be reused. It also gives the possibility to not use GNAT Studio at all and enjoy Ada functionality in a number of other IDEs.

Check out this video to see how these new changes make GNAT Studio more efficient, more reliable, and more maintainable.

Engineering Self-Verified Software

By: AdaCore
8 July 2021 at 15:52

Implementation and verification are traditionally viewed as two separate activities. Even in test-driven environments, the test platform is distinct from the implementation one. This talk will present an alternative approach where the verification and development activities are engineered together, creating effectively a “self-verified” program combining at the same place an implementation and the means to verify its correctness.

4 key takeaways
- Developing verification at the same time as the code allows for more efficient coding processes and mitigates errors at the end of the process.
- Formal proofs and testing can be combined to increase the level of safety and decrease overall development costs.
- There are alternatives to the C programming language that allows more effective verification.
- There is a way to redirect software developers energy from worrying about low-level coding errors to concentrate on more valuable aspects of software engineering.
