According to the invention, the operating softwareof a technical system, particularly of a controller for controlling or regulating at least one technical device, is modified by virtue of hardware-dependent software components in the operating softwareexecutable directly on the technical system not being executed and instead the functional behavior of the hardware-dependent software components being recreated by substitute functions. To this end, the hardware-dependent software components are automatically identified (step S), and the substitute functionsare automatically ascertained or produced. On execution in a suitable simulation environment(step S), the operating softwaremodified in this way simulates the technical system independently of the real hardwarethereof.

Modifying and simulating the operating software of a technical system

An interface unit for data exchange between a first processor of a computer system and a peripheral environment. The interface unit has a number of input data channels for receiving input data from the peripheral environment and a first access management unit. The access management unit is configured to receive a request for providing the input data, stored in the number of input data channels, from a first interface processor stored in the interface unit and from a second interface processor stored in the interface unit and to provide or not to provide the input data, stored in the number of input data channels, to the first interface processor and the second interface processor. A first priority and a second priority can be stored in the first access management unit.

Interface unit for routing prioritized input data to a processor

A method for configuring an interface unit of a computer system with a first processor and a second processor stored in the interface unit. A data link is set up between the first processor and the second processor. A peripheral of the computer system is configured to store input data in an input data channel and to read output data from an output data channel, and the second processor is configured to read the input data from the input data channel and to store output data in the output data channel. A sequence of processor commands for the second processor is created such that a number of subsequences is created.

Method for configuring an interface unit of a computer system

A testing device for real-time testing of at least a part of a virtual electronic control unit with an electronic control unit code is provided. The testing device has a computing unit of a first type, and a computing unit of a second type. The testing of a virtual electronic control unit with electronic control unit code, which is executable on the computing unit of the second type with a second instruction set, is made possible in that a computing unit of the first type executes an emulator for emulating the computing unit of the second type and the emulator executes the electronic control unit code. The emulator also has a simulation environment interface for exchanging data and/or events with the simulation environment.

Testing device for real-time testing of a virtual control unit

An adjustment device for adjusting at least one control device with at least one control device microcontroller and with at least one control device debug interface, where the adjustment device comprises at least one programmable unit, at least one data transmission interface for connecting the adjustment device to an operating unit, and at least one adjustment device debug interface for connecting the adjustment device to the control device debug interface of the control device. The adjustment device according to the invention accomplishes the objective of reducing the load on the control device due to control device application by at least one address list and at least one data list, which are provided in a memory of the adjustment device.

Influencing device for control apparatus

The present invention relates to a test device for testing a control system and an associated method for operating the test device. The test device includes an addressable memory. The test device is configured to calculate at least one environment model and to execute at least one test model. The environment model is described by environment model variables whose values are filed at fixed physical addresses in memory locations of the memory. The test device further comprises an allocation unit, in which the allocation of all or a part of the environment model variable to the allocated physical addresses of the memory is filed such that the test model can read the allocation of the environment model variables to their specific memory addresses so as to modify the environment model variable values in the environment model during its execution.

System for testing at least one electronic control unit and method

A method is presented and described for testing of at least one electronic control system, in which the control system is connected via a data channel to a test device, at least one environmental model is calculated on the test device and the environmental model interacts with the control system by output of environment model data via the test device to the control system and by receiving control system data from the control system via the data channel. The method according to the invention executes on the test device at least one test model to influence the environment model and/or to calculate the environment model and/or the electronic control system, in which the test model or the test models is or are executed functionally independently of the environment model and, during test operation, synchronously with the environment model.

Method for testing an electronic control system

A method for synchronously providing data on distributed devices of a network includes storing, by a master device, an extrapolation data set including at least one update time point. The update time point is in the future and marks the beginning of an extrapolation interval. The master device transmits the extrapolation data set to a slave device. Starting at an update time point, new data is calculated separately on the master device and the slave device by extrapolation using the extrapolation data set available on both the master device and the slave device. The method steps are repeated for subsequent extrapolation intervals.
