See What Our Customers Are Saying

Harmonic Software Systems worked as the Test Lead in a large DO-178C, level A certification project. They joined the project right from the beginning and wrote the test harness for PPC, hence  paving the way for the rest of the test team (~25  testers). During the project, Ed was the go-to person for difficult technical problems and safety considerations on testing, and he always was able to solve it. He has very strong technical and communication skills, and it is always good to work with him.

HSS worked on a project whereby they needed to implement a new PPC architecture (the 8 core P4080) for the VxWorks RTOS and develop a BSP with very complicated hardware. This was no easy job and they managed to get it done by diving very deep into the matter and solved many problems on the way.

Project Manager (Aerospace & Defence), Wind River Services

Harmonic Software Systems did the heavy lifting to get our safety critical medical device working, allowing us to concentrate on coding without specific VxWorks training. Harmonic exceeded expectations in their dedication to our project and in applying their extensive experience, enabling us to meet our tight deadlines.

White Paper

The cover of the White Paper: Fix, Develop & Test Embedded Software In A Game Changing Way | A DO-178C Software Blueprint For The Aerospace & Defence Industry

Fix, Develop & Test Embedded Software In A Game Changing Way | A DO-178C Software Blueprint For The Aerospace & Defence Industry

This backgrounder whitepaper defines an ecosystem of software tools that work in synergy to provide a powerful reproducible system for delivering DO-178C projects. It looks at the current landscape of software used and the inherent problems within the existing approach. Its purpose is to demonstrate a world-class collective of software tools and optimal workflows to be used at the organisational and human level.

The software ecosystem proposed is that used by Harmonic Software Systems and has evolved over many years and projects. Ultimately, the whitepaper seeks to provide a solution to the problem of embedded software that is ‘not fit for purpose’ because it doesn’t work or meet requirements and is therefore DO-178C non-certifiable.

Such is the complexity and difficulty of landing DO-178C projects on time and budget; the whitepaper advises on how to deliver superior embedded software solutions so clients are both profitable and delighted. We would love your feedback. Thanks
