ISO 26262 compliant safety concept design tool for SCDL
This is a modeling tool that supports the design of safety concepts and facilitates smooth information sharing between designers and developers. It adopts the Safety Concept Description Language (SCDL), which is based on specifications and standards established by the "Safety Concept Notation Research Group SCN-SG." Safety concepts can be described using an editor with block diagrams, promoting common consensus and sharing. **Features** Safilia is designed for use by product development department designers during the design phase of the V-model process when designing safety concepts. It communicates and shares safety concepts within departments and organizations using a unified notation. If safety evaluations reveal deficiencies in safety design after the prototype model is completed, due to insufficient communication of design intentions based on safety concepts, significant "rework" may occur, such as changes to specifications or the design itself. By enabling early development and evaluation of safety design using standardized notation, Safilia can prevent significant losses caused by rework.

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.
