Because this was the first time we had used Polyspace products on an IEC —governed project, we made the decision early on to conduct a manual review in parallel lec the Polyspace verification. Expanding the Use of Polyspace Code Verification.

We had to set up a new, highly sophisticated development process that would enable us to satisfy IEC requirements. Each instance was deemed justified because we knew exactly what was causing the Polyspace code verifier to mark it as unreachable code.

For example, they may highlight the use of absolute memory addresses, which are sometimes hard-coded in embedded software.

MTU build engineers also ran the Polyspace code verifiers as part of the automated nightly build and test process, using the results to identify areas of code that needed more developer attention. When we began developing the control software, we had relatively little in-house expertise in IEC requirements. The plan comprised three core areas: However, even the most detailed results are insufficient evidence for regulatory authorities and our customers that the software fulfills the requirements of the standard.


Worldwide Standards We can source any standard from anywhere in the world. Polyspace code verifiers highlight each element in the code as green, red, gray, or orange to indicate its status.

Polyspace code verifiers highlight code that is proven to be free of certain categories of run-time errors, enabling the team to focus their reviews on the remaining code. Section 8 ief Software verification. This contains everything needed to prove that our tools fulfill IEC recommendations as well as guidance to help you to achieve compliance.

For the third area, we documented our own use of Polyspace code verifiers and combined this with additional Polyspace product usage information so that we could adapt the certification kit based on our own use cases.

Our initial strategy was to use our standard commercial software development process while producing more documentation and conducting additional tests—including Polyspace tests for run-time errors idc some of our legacy code.
