What is an A2L file?
Standard file format specified by the ASAM MCD-2MC (ASAP2) workgroup; describes the interfaces, measurements, and parameters of an Electronic Control Unit (ECU), an electronics component that is used to control various parts of a motor vehicle; helps in the process of transforming an ECU model design into a physical ECU; also helps in the process of calibrating and testing the ECU.
The A2L format has been adopted widely by the "xCU" development, testing, and calibration community. It is used by products such as AVL CRETA Calibration Data Management, a solution for the calibration of powertrain systems (automobile propulsion).
