The process of developing new functions and software for powertrain embedded control units (ECUs) is undergoing a sea change. One of the reasons is the pressure to meet regulatory requirements (e.g. emissions, fuel economy) in addition to managing the normal growth in software complexity. Traditionally, the vehicle manufacturer (OEM) would write new specifications and hand them over to the software supplier (Tier1). This process required a substantial review and testing process at the OEM to ensure that the requirements were interpreted and implemented as indented. Today, a number of parties are involved in creating specifications (including the software supplier and 3rd party engineering companies), thus making the verification task even more complex.
