Building a MOST infotainment system in a heterogeneous networking environment
The rapid progress of consumer electronics forces car manufacturers to reduce Time-to-Market (TTM) when creating a new infotainment system or implementing new features in existing systems. The growing value of software in the automotive industry and the complexity of modern systems both increase the importance of the software development process.
describe the network protocol. The generator supports CAN DBC, LIN Description File (LDF) and a MOST XML function catalog. MAG.NET generates .NET classes that represent the messages for CAN, MOST and LIN protocols. The generated code for the LIN protocol includes the driver configuration as well. The code generated from a MOST XML file also contains the .NET classes that implement the default behavior for both sides of the communication: the controller/shadow (client) and the slave/FBlock (server).

Modern techniques, which include, for example, parameterized tests, are widely spread in the .NET environment, and can reduce the development efforts for the automated tests.

K2L ATS is well-suited for testing and simulation of the traditional infotainment system as a set of devices that are built into the vehicle and communicate over MOST, CAN and LIN. Some of these devices can have a pair-to-pair connection to the end-user devices, for example, over Bluetooth.

Convergence of Automotive and Consumer Electronics

As has been mentioned before, future infotainment systems require a tool for support of the convergence between automotive and consumer electronics over computer networks. There are several variants of networking topologies regarding how consumer electronic devices such as mobile phones, tablets and laptops and the infotainment system could be connected. The simplest topology is that the car has its own mobile broadband Internet connection and its own Wi-Fi hot spot. This provides access to the Internet and remote automotive services. Another topology is an analog to the Bring-Your-Own-Device (BYOD) concept. Here, the infotainment system has a Wi-Fi network interface and connects to the hot spot provided by the customer mobile device, which has Internet access over a cellular network.

The principal difference between these two topologies is that in the first case the infotainment system communicates with the service endpoints in the Internet directly, whereas in the second case the network
