Applications/Examples of results
We support methods that relate both FTA and ATA to individual or mutual analysis. In particular, it is possible to describe the AT diagram within the FT diagram in the descriptions of the FT diagram and the AT diagram. Additionally, we provide support for modularization through package implementation, and the AT diagram includes risk assessment functions, facilitating EVITA-style analysis. By visualizing threat analysis, it becomes easier to reach consensus on design quality in documents and to quantify and numerically assess threats.

Company information
Gaio Technology started in 1980 with the in-house development of cross-compilers for embedded development and has since provided testing tools for embedded software based on microcontroller code analysis technology and simulation technology. Furthermore, the company has expanded its engineering services business and is currently engaged in model-based development support, test process construction support, and tool implementation and operation support for major automobile manufacturers and large automotive parts suppliers. The unit testing tools for embedded software, "Coverage Master winAMS" and "CasePlayer2," are representative tool products of Gaio, with many users. They have a mechanism that allows testing to be conducted in the state of implementation in the product without modifying the software (microcontroller code) installed in embedded products, receiving significant support from the automotive control software field, which demands high software quality to ensure safety. The tools have obtained certification for automotive functional safety (ISO 26262) and have now become the de facto standard for automotive software unit testing tools.
