Transcription

1 Test and Simulation 14 th MOST Interconnectivity Conference Asia 2013, November 14 th Tokyo, Japan 1

2 Test and Simulation Motivation Systems Engineering today Challenges tomorrow Higher integration of devices Devices and systems are even more networked Complexity of development projects increases Leads to higher effort on the verification side Impacts quality and time to market V Modell approach is state of the art Several stages in a serial row Proven for devices and self contained systems Delivered appropriate results so far? Does V Modell approach cover the future needs? 2

8 Typcial E/E system development process The evolution of the general E/E system conditions E/E systems today the challenges E/E system architecture Upto 100 ECUs 5+ fieldbusses ECU architecture 32/64Bit multicore MCUs, FPGAs Realtime operating systems Software code of several Mbytes CE device integration Becomes more and more important Market windows becomes smaller Development process Development cycle time Steadily decreasing Only 3-5 years for systems 2-3 years devices Development process Waterfall process is not used any longer V modell is state of the art Does development process match the challenges? 8

9 Typical E/E system development process Status review Today s software development process for in-vehicle systems engineering V Model Still with many waterfall characteristics, one stage after the other Inter-path relationsships Validation against spec MIL, SIL, HIL Nonetheless Still to much effort spent for Why? Safeguarding Device verification System integration Cycles between left-right path are too long In-the-Loop techniques are helpful, but still not enough, and rather late in the process Software needs to wait on hardware Development process improvement needed!!! 9

10 Typical E/E system development process Improvement proposal How can the situation be improved? Much earlier testing in the development process Multiple testing within the development stage Early testing against simulations Device simulations Restbus simulations Comprehensive tool chain Stronger focus on Test & Simulation 10

11 The new E/E system development process Test and Simulation Restbussimulation Simulation based Testing Comprehensive toolchain Implementation support Test & Simulation influences/enables the development process Good simulations enables early testing Standard techniques enables more users Consistent workflow enables more stakeholders More toolchains enable more adopters core of the development process the dev process nerve center 11

18 MOST PCI Tool Kit With MOST Stream MOST Stream: Graphical User Interface to read audio/video data from a file for streaming on the network (synchronous or isochronous) and to store received data into a file on PC 18

19 MOST PCI Tool Kit MOST Stream Send and Receive in parallel on several MOST Channels Send data from PC file on MOST network Receive Streams and save into a PC file 19

20 MOST PCI Tool Kit Demonstration Video Streaming Efficient testing of streaming in both directions TV Tuner 17/11/

21 Conclusion and outlook Big changes in system architectures and increase in complexity Typical E/E system development process (V model) still the right approach, but more focus needed on Test & Simulation Test &Simulation is the new nerve center This will improve getting along with complexity and shorten time to market K2L products can help changing the focus K2L is open for discussion in any direction concerning Test & Simulation 21
