Classification of instrumentation and control functions. Test framework generation Test case generation Test execution Results diagnostics and report generation.

We use Polyspace products to verify the generated code.

The detailed results made it easier to identify problems with our code and to justify unproven or unreachable code. 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 on 6126 of our legacy code.

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 with the Polyspace verification.

The Normative Annex B5. After integrating all the code into the version control system, we ran Polyspace code verifiers to recheck the entire code base. Agencies and customers needed proof that we had a plan for software development, that the tools we used were qualified, and that we had followed the plan and used the tools correctly. QA Systems enables organisations to accelerate IEC compliance with automated static and dynamic testing tools:.

For example, they may highlight the use of isc memory addresses, which are sometimes hard-coded in embedded software. Static testing for IEC compliance. IEC defines requirements for 661226 software used in computer-based instrumentation and nuclear power plant control systems—specifically, software that performs functions of safety category A, as defined by IEC In our code, a few lines were marked red, meaning they were proven faulty but justified as correct and valid statements.

Other MathWorks country sites are not optimized for visits from your location.

Dynamic testing for IEC compliance. Your basket is empty.

Take the smart route to manage medical device compliance. Instrumentation and control systems important to safety. A key element of our new software development process was tool chain managementan area concerned with the selection and qualification of software development and testing tools.

For the first area, correct tool function, we used test cases, procedures, expected results, and other qualification artifacts from DO Qualification Kit and IEC Certification Kit Figure 2.

For example, as a defensive programming practice, the developers implemented each switch statement in C with a default option that could not be reached via normal operation.

Please contact us for more information on Cantata for IEC When we began developing the control software, we had relatively little in-house expertise in IEC requirements. This contains everything needed to prove that our tools fulfill IEC recommendations as well as guidance to help you to achieve compliance. Chapter 14 of IEC covers the appropriate use of software tools, including those that can increase the integrity of the software development process and improve software reliability.


Section 8 – Software verification. 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. We use cookies to make our website easier to use and to better understand your needs.

We had to set up a new, highly sophisticated development process that would enable us to satisfy IEC requirements.

QA-Verify adds reporting to ensure this over time and across product versions. Cantata Team Reporting Test status management dashboard add-on.

Worldwide Standards We can source any standard from anywhere 612226 the world. You may experience issues viewing this site in Internet Explorer 9, 10 or However, even the most detailed results are insufficient evidence for regulatory authorities and our customers that the software fulfills the requirements of the standard.

A formal review team checked and justified each oec element marked as red, orange, or gray. 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.

Each instance was deemed justified because we knew exactly what was causing the Polyspace code verifier to mark it as unreachable code. Each of these elements, however, had to be justified, which meant explaining why it was not an issue. Please contact us for more information about ie certification kits.
