Modena v 5.1.0 facilitates specification and testing of infotainment ECUs

July 19, 2011 // By Christoph Hammerschmidt
Automotive engineering company Berner & Mattner presents Modena 5.1.0 as an extended version of its specification and test software for model-based development in automotive infotainment, thus increasing the application range for users. In the MOST area, the new version of Modena supports selected stress features and the MOST High Protocol in accordance with the MOST High Protocol specification 2.3. In addition, Modena now includes a separate event for processing CAN error frames.

Modena developers and testers can use the system for specifying and testing ECU functions, ECU communication and embedded systems with accessibility to CAN, LIN, MOST25 and MOST150 by means of market-based hardware. Characteristic Modena features include early simulation of generated specifications, the use of specification models in virtual and real networks as well as the reuse of test cases for testing the real ECUs.

As of now, Modena supports improved testing with the following stress features of the hardware interfaces for the control channel: "Light," "Lock", "Bus Load" and "Receive Buffer Full". Starting and stopping of the stress features is carried out in Modena. Moreover, low-level retries can now be configured for the hardware interfaces. Here, the number and time between each low-level retry can be defined within Modena. Furthermore, Modena 5.1.0 now also supports the Lock event in the simulation - in addition to the already existing Light event.
