Software integration tests for embedded systems must cater for the physical process with which the systems interact and can include user input. This can make testing very time-consuming because test engineers often manually execute test specifications with many thousand lines of instructions. Furthermore, such manual tests are often imprecise because human operators cannot execute interactions at...
To reduce the development cycle time and cost of the transmission control unit (TCU) for automated manual transmission (AMT), a rapid testing platform (RTP) based on the concept of hardware-in-the-loop simulation is introduced and implemented in this paper. The proposed RTP features that the vehicle parts in simulation are all model-based. The torque characteristic of engine, the mechanical characteristic...
In this paper, an efficient control system development method based on real-time virtual hardware-in-the-loop simulation is presented. Instead of developing and testing control system after physical prototype is produced, it can be conducted immediately after concept of controlled system is designed by developing a pure software real-time simulator. In this simulator, all the hardware is virtual....
The potential of applying search-based testing principles to functional testing has been demonstrated in various cases. The focus was mainly on simulating the system under test using a model or compiled source code in order to evaluate test cases. However, in many cases only the final hardware unit is available for testing. This research presents an approach in which evolutionary functional testing...
Evolutionary Functional Testing (EFT) is a relatively recent approach to automating the testing process. The research presented in this paper aims at increasing the acceptability of EFT in industrial settings. An approach suitable for efficiently and effectively testing complex continuous control systems is introduced. The main focus is on generating realistic test stimuli, enabling interactivity...
Succinct test script with high efficiency is one of key point for automation of embedded software testing. In this paper, we integrated object technique with automated simulation testing to propose an object-based embedded software simulation test script language (OESSTSL) and gave its features, formal description and supporting mechanism for automated embedded software simulation testing, furthermore,...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
Hundreds of memory instances and their frequency of operation have ruled out the possibility of sharing test structures amongst the embedded memories. This paper discusses the techniques and flow for sharing an embedded memory BIST for the at- speed testing of multiple memories on a typical SoC.
