Today iSYSTEM presented a concept and associated tool setup enabling users of iSYSTEM tools to show proof that the deployed tools work as specified.
ISO26262 is a standard that ensures functional safety in road vehicles. Parts of this specification describe provisions that automobile suppliers and/or manufacturers must fulfill in order to “minimize the risk of systematic faults in the developed product due to malfunctions of the software tool (introduce or fail to detect errors). Hence qualification has to be accomplished for software tools used in the development and test process before the actual development starts.
To implement the standard's requirements at customer side, iSYSTEM offers organizational measures and documentation as well as a tool setup for the validation of dedicated tool functionality.
One organizational measure is for instance detailed documentation about the iSYSTEM tool development and test process. Basically it is an individual safety manual adapted to the needs of a customer and contains for example:
- Tool features-/functions descriptions that are used in a safety project
- Explanations how these functions should be used
- Manuals on the application of software and hardware, “Getting Started Guides”, etc.
- Descriptions on the system prerequisites in general and in reference to the target processor
- Descriptions on well-known workarounds for a specific micro controller
The safety manual informs the developer how to use iSYSTEM tools for the development of safety critical applications.
If a specific function of an iSYSTEM tool has to get validated based on ISO26262, iSYSTEM provides a “Tool Pre-Qualification Kit”. This consists of reference hardware plus test cases to validate several functions of an on-chip debug and trace tool such as:
- Standard debugging and IDE functions, e.g. memory read, write, step, memory dump, download, flash programming, etc.
- Advanced debugging with trace and profiling (especially time measurements)
- Software test with code coverage and unit test
This allows iSYSTEM customers to show the proof that iSYSTEM tools perfectly fit in the context of a safety project as required by the ISO 26262 standard.
