Embedded Software Unit Testing "Coverage Master winAMS"
Coverage Master winAMS: Unit Testing Tool for Windows Development Environment
Coverage measurement tool 'used by everyone' for embedded software development unit testing
"Coverage Master winAMS" is a unit testing tool for embedded software in C/C++ that complies with the functional safety standards ISO 26262 / IEC 61508, capable of measuring code coverage such as statement, branch, MC/DC, and function calls. It includes a microcontroller simulator that executes the compiled object code for unit testing. Unlike typical unit testing tools that are limited to logical-level unit testing of C source code, it conducts the most faithful and reliable unit tests on microcontroller code, including issues dependent on the implementation specific to embedded systems. (Supports C++ 11/14) 【Features】 - Executes unit tests based on "actual machine code," leading to increased efficiency - Fully supports C0, C1, and MC/DC coverage, as well as function/call coverage measurement during the integration phase - Efficiently generates test data from both white-box and black-box perspectives - Seamlessly creates, executes, and verifies coverage comprehensive test data within the tool - Provides options for efficiently conducting Back to Back testing

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.
