Tool Qualification Kit
for Safety-Critical Software

A custom, comprehensive qualification tool to gain the confidence you need to ensure your test processes meet safety standards.

For safety-critical software, like those dealing with electronic systems in automotive systems, safety protocols mandate that the tools involved in test processes be qualified in order to reach such standards. Qt therefore offers a Tool Qualification Kit for Squish Coco, a comprehensive, procedural approach to validating the tool’s behavior, tailored to the user’s processes, test environment and the safety protocols relevant to the software. Each kit we offer is designed on a case-by-case basis, fully customized to the safety context of your software, and results in a set of documents that can be made available to the appropriate authorities for tool qualification in order to reach a safety-critical standard.

Qt offers Tool Qualification Kits for several standards, including:

  • ISO 26262: Road Vehicles – Functional Safety
  • EN 50128: Railway Applications
  • DO-330: for Airborne Systems subject to DO-178C and DO-278A
  • IEC 61508: Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems
  • IEC 62304: Medical Device Software – Software Life Cycle Processes
  • ISO 13485: Medical Devices – Quality Management Systems

How It Works

Qt works with the customer to design a custom Tool Qualification Report which can be delivered as a proof of a successful tool qualification process. This report, based on the client’s concrete use case and the requirements of the standard, is authored in tandem with the customer and Qt, and details the comprehensive, procedural steps in the qualification process. It contains a description of Squish Coco, the security measures a user needs to take in using the tool, and a list of tests a user must perform to ensure that Coco works correctly on their system. Qt then provides each customer with a validator program, which executes these tests against Coco, based on a custom configuration which is guided by the customer’s specific use case. Upon successful validation, the validator will emit a report reviewing the test suite’s pass and failure status.


Build the trust and gain the confidence you need in your testing workflow.

The use of the Tool Qualification Kit offers several benefits, those chiefly being:

  • Increased assurance of Coco’s use in your development processes.
  • Significant savings in costs associated with having to dedicate time in preparing custom reports required by the standard.
  • Reduction in the potential for human-error associated with manual qualification.
  • The results of the qualification kit serve as internal and external documentation, and make the test processes of the team fully transparent.
  • Peace of mind during routine auditing by authorities in control of safety-critical standards.
