A method in which the propagation times of a target network are simulated in an actual network, wherein the topology of the target network includes a number of senders and a number of receivers, and wherein the topology of the actual network includes one or more of the senders and receivers. A path between a first sender and a first receiver in the topology of the actual network differs from the path between the first sender and the first receiver in the topology of the target network, wherein in the actual network at least one first message of the first sender is received through a first network interface by a gateway having at least two network interfaces, is delayed by a delay, and is sent through a second network interface on a path to the first receiver.


A method for accessing signals of a programmable logic device having a functional level and a configuration level at run time when the programmable logic device is executing a predefined configuration. An access to at least one signal value that has a number of bits is requested. The individual bits in the configuration are each located in an address unit with one address offset apiece such that one or more bits of a signal value are located in one address unit. A bitwise access to the requested signal values takes place, wherein the accesses to the individual bits are sorted as a function of the address unit containing the applicable bit in such a manner that the accesses to all bits located in an address unit take place in sequence as a function of the address offset, independently of the signal containing the applicable bit.


A method for determining the power consumption of a programmable logic device, in which at least one configuration parameter is determined in accordance with a predefined configuration and at least one device parameter is determined in accordance with the programmable logic device. The predefined configuration is designed such that the programmable logic device exchanges data with a computing unit through at least one interface pin and receives data from at least one signal source and/or sends it to at least one signal receiver through at least one interface pin. At least one data characteristic of the data exchanged between the computing unit and the programmable logic device as well as at least one signal characteristic of the data received from the at least one signal source and/or sent to the at least one signal receiver are determined.


A simulation apparatus for simulating a peripheral circuit arrangement connected to a regulating device and has a first current controller for influencing a first load current and a second current controller for influencing a first source current. The first current controller is controlled by a model code and used to set the first load current, and the first load current is routed to a first load connection of the regulating device. The second current controller is controlled by the model code and used to set the first source current, which is routed to a first supply connection of the regulating device. The model code influences the model code on the first current controller and the second current controller allows the first load current to be recovered at least proportionally from the first source current and/or the first source current to be recovered at least proportionally from the first load current.

A transfer of payload data from a buffer to a destination data store is provided so that the data can be processed there by a computer-assisted development environment. To this end, a data management environment provides the buffer and the destination data store. A data record having the payload data and semantic data that are associated with the payload data is provided in the buffer, and a data object with processing-specific object semantics is provided in the destination data store. The data object is instantiated with the payload data by means of the semantic data in that the payload data are placed in the data object as a function of the object semantics of the data object in such a manner that the development environment can process the payload data on the basis of the object semantics.

The invention relates to a method in which propagation times of a nominal network are simulated in a real network, wherein the topology of the nominal network comprises a plurality of senders and a plurality of receivers, the topology of the real network comprises one or more of the senders and receivers, the path between a first sender (10) and a first receiver (12) in the topology of the real network differs from the path between the first sender and the first receiver in the topology of the nominal network, at least one first message from the first sender (10) is received in the real network via a first network interface by a gateway (2) with at least two network interfaces, is delayed by a first delay and sent via a second network interface on a path to the first receiver, the path of the first message is determined by the topology of the real network and the delay of the message is determined according to the topology of the nominal network in such a way that the propagation time of the first message in the real network is essentially the same as the propagation time of the first message in the nominal network.


A computer-implemented method for implementing a V2X application on target hardware having a radio adapter, wherein the V2X application is modeled in the form of a block diagram by means of a graphical modeling environment and the block diagram is compiled into a V2X program that can be executed on the target hardware and the V2X program is transferred to the target hardware and executed there. The method for implementing a V2X application is realized in an especially simple and advantageous manner in that a V2X communication block that has at least one radio adapter interface, by means of which data are exchanged between the radio adapter and the V2X communication block, is used to create the block diagram.


A test bench for testing a distance radar instrument for determining distance and speed of obstacles, comprising a radar emulation device comprising at least one radar antenna and a computer unit with a model of the surroundings, wherein the model of the surroundings comprises data (x, v) of at least one obstacle with a relative position and speed from the distance radar instrument, wherein the radar emulation device emits a suitable reflection radar signal on the basis of the relative position and speed predetermined by the model of the surroundings at least partly in the direction of the distance radar instrument after receiving a scanning radar signal from the distance radar instrument such that the distance radar instrument detects an obstacle with a predetermined relative position and speed, wherein the radar emulation device extends over an angular range in front of the distance radar instrument such that the obstacle with relative position and speed can be simulated in this angular range with mutually distinguishable angles.

A method for manipulating a first function of a control program of an electronic control device, using a second function. The control program is processed using a first calculation kernel of a processor, and the second function is processed by a second calculation kernel during the processing of the control program. The first function assigns a first value to a variable and writes the first value to the storage address of the variable at a first time. The second function assigns a second value to the variable, which value is written to the storage address of the variable at a second time, wherein the second value written by the first function is overwritten. At a third time, the control program reads the second value from the storage address of the variable. A control entity coordinates the times at which the storage address of the variable is accessed.
