According to Mathworks, Matlab Coder eliminates the need to manually translate Matlab algorithm code into C and C++ code for prototyping, implementation, and software integration. This results in a faster, more efficient system-development workflow.

The design of algorithm-intensive electronic and communications systems typically begins with Matlab. The Matlab algorithms eventually need to be converted into C code for integration into the final product. Manually converting from Matlab to C can take from days to weeks, introduce design errors, and contribute to time-to-market delays. Design engineers now can use Matlab to speed up development tasks such as fixed-point design and prototyping, and automatically generate C code with Matlab Coder.

The software tool supports an extensive set of Matlab language features for algorithm development, including built-in matrix math operators and dynamic array handling. Hundreds of operators, functions, and System objects are supported, including advanced algorithms for DSP and communications.

Along with the introduction of Matlab Coder, MathWorks released Simulink Coder and Embedded Coder. These two products simplify code generation for Simulink and Stateflow users by combining capabilities previously available in multiple MathWorks offerings. The new products incorporate the Real-Time Workshop technology, and offer full code generation support for rapid prototyping, real-time testing, and production embedded system implementation with built-in links to embedded development environments.

At the same time, the software vendor announced that TÜV SÜD certified Simulink Design Verifier and Simulink Verification and Validation for use in ISO 26262 compliant development processes. This independent assessment helps automotive engineers developing high-integrity embedded systems to establish the required confidence in the proper functioning of these verification tools according to their use cases.

MathWorks classified and prequalified the automatic test case generation capability of Simulink Design Verifier and the model coverage measurement capability of Simulink Verification and Validation according to the latest version of ISO 26262-8. TÜV SÜD subsequently assessed the tool classifications and prequalification results. To further assist automotive engineers using early verification and validation for Model-Based Design, MathWorks enhanced the IEC Certification Kit product with certification evidence, reference workflows, and ISO 26262 tool qualification artifact templates for Simulink Design Verifier and Simulink Verification and Validation. With these recent additions, the IEC Certification Kit extends ISO 26262 tool qualification support for Model-Based Design and verification products, which already includes Embedded Coder and Polyspace code verifiers.

To support additional activities addressed by the ISO 26262 functional safety standard, MathWorks said it will continue to work closely with partners offering complementary technology. As an example, medini analyze, a functional safety analysis tool offered by ikv++ technologies AG, can be used to automate automotive safety integrity level (ASIL) determination and decomposition as well as detailed safety analysis activities as required by ISO 26262 when developing high-integrity systems using Simulink.
