We are QTronic
We are an experienced team of engineers, computer scientists, physicists, and mathematicians. At our offices in Berlin, Stuttgart, Munich, Cluj-Napoca, and Beijing, we passionately work on the development and introduction of new tools for the simulation-based development of vehicle systems.
The idea behind QTronic
Nowadays, a typical car contains software with 100 to 150 million lines of code, distributed across 30 to 80 ECUs, and about 30.000 physical components. This puts vehicles among the most complex technical systems on the world. The rapidly growing size of the software stack and the complex interaction of software and physical components creates an enormous challenge for automobile manufacturers and their suppliers.
QTronic offers development tools and services to manage this new kind of complexity.
We provide tools and services to develop vehicle software faster, safer, and better than others. Our approach: To master the complexity of software-intensive vehicle systems, the development process should be virtualized by shifting software development steps from prototype vehicles, test rigs and HiL (hardware in the loop) to the PC of the function developer.
As a result, the software can be tested simultaneously at many work seats (in parallel), and in a highly available, comfortable and relatively inexpensive environment (Windows PC). Virtualization enables a tremendous increase in test coverage. This increases the safety of the development process and reduces the risk of critical error being undetected during development. Moreover, errors are detected earlier in the process. This makes the troubleshooting cheaper. The idea is also known as “frontloading” of validation and test. The picture below shows the virtual development process. QTronic’s business is entirely within the green disc.
The technical basis for virtualization is simulation technology, which has also developed rapidly in the last decade. Essentially, QTronic develops and sells two tools:
- Silver is a tool for creating and running virtual ECUs. A virtual ECU is a model of a real electronic control unit that executes most of the ECU’s software and provides very similar interfaces of a real one. Silver is used to virtualize the development of automotive software. Today, Silver is the market leader for virtual ECUs. In fact, Silver (first released in May 2008) was the first such tool on the market.
- TestWeaver is used for large-coverage testing of automotive software, typically in combination with Silver virtual ECUs. TestWeaver is our solution for test automation and used to implement “frontloading” of validation and test.
