Software tool verification and certification support report creation service at a level expected for TCL2 ~ 3

This service verifies software tools such as compilers that are TCL2 to 3 in system development that is classified as ASIL C or higher in ISO26262. We will create a tool certification support report that includes not only the verification results but also documents to show the validity of the verification and data such as workarounds for defects.

Service contents

We support software tool certification work for applicable software required by ISO 26262: 2011.

[1] Verification of applicable software

Comprehensive software testing can be a huge amount of combinatorial testing. By creating effective and efficient test cases that assume operation from functional specifications, manuals, and use cases, we will provide verification data that is convincing to certification bodies, even if it is not a huge combination test, and workarounds. In addition, by narrowing down the test cases, quality verification can be performed in a short period of time, and it is possible to reduce the cost related to software verification.
