For most applications compliant with IEC 61508 and its derivatives (IEC 62304, EN 51208, ISO 13849...) the existence of a TUV certification is adequate evidence of the suitability of software test tools. However, for more demanding applications (and optionally, for less demanding ASILs) these standards do not provide details of how tool qualification should be achieved in the context of a project tool chain . Learn how the qualification processes described by DO-330 and ISO 26262 can be applied using LDRA tools to help ease the path to tool qualification.
