Flextech Solutions LLC began in November of 2005 to serve the growing need for a way to test and qualify automotive ECUs. This requires simulating the rest of the system or vehicle over the in-vehicle network, which is typically the CAN bus. We make tools to simulate CAN bus common mode messages in order to meet the enable criteria for the ECUs to function normally and be configured. This allows us to break out actuators and sensors so that all test cases can be performed prior to vehicle launch. We have continued to evolve over the years, offering one of the first CAN-FD tools and simulators on the market in 2018. In addition, we are engaged in the digital domain creating systems with Base100T and Base1G Automotive Ethernet for a variety of software stacks. We make custom tools for A2B digital audio bus, as well as offering custom audio applications for functional testing and automation.
