Abstract: A method for providing a timestamp in a real-time system, whereby the real-time system has an FPGA and a CPU, which cooperate with one another, and at least one register, which contains a system time, is implemented in the FPGA. The method includes the steps of providing a CPU counter for the system time, which is driven by a clock signal of the CPU, providing a synchronization counter in the CPU, whereby the synchronization counter is driven by a clock signal of the CPU, reading of the counter for providing the system time by a real-time application, querying the synchronization counter in the real-time application, and synchronizing the counter with the system time in the real-time application, when the synchronization counter outputs a value that corresponds to more than a predefined time period since the last synchronization of the CPU counter with the system time.

Abstract: 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.

Abstract: A method is presented and described for testing of at least one electronic control system (1), in which the control system (1) is connected via a data channel (2) to a test device (3), at least one environment model (4) is calculated on a test device (3) and the environment model (4) interacts with the control system (1) by output of environment model data via test device (3) to control system (1) and by receiving control system data from control system (1) via data channel (2). The method according to the invention prevents the drawbacks known in the prior art by executing on test device (3) at least one test model (5) to influence the environment model (4) and/or to calculate the environment model (4) and/or the electronic control system (1), in which the test model (5) or the test models (5a, 5b) is or are executed functionally independently of the environment model (4) and, during test operation, synchronously with the environment model (4).

Abstract: A method and a device for the dynamic treatment of objects in a test design are described and presented. According to this method, the test design comprises at least two bidirectionally exchanging systems and at least one additional system to be tested. Objects of a first type belong to an environment model, which is executed on a first system, and these objects can be processed by a test model. The inventive method prevents the drawbacks known from the prior art, in that objects of a second type that are similar or identical to the objects of the first type are generated; and the objects of a first and a second type are made available to at least one of the systems by means of a management device.
