Abstract: The invention relates to a method for generating a simulation program which can be executed on a computer for the purpose of simulating the function and execution time of a program which is provided to be executed on a target computer, the method comprising the following steps of: a) providing a source code of the program, b) producing an optimized intermediate representation of the program's source code, c) determining execution times on the basis of the optimized intermediate representation of the program's source code, d) generating an object code, which can be executed on a host computer, on the basis of the optimized intermediate representation of the source code and then e) combining the execution times, the object code and a prescribed simulation library using a linker, such that a simulation program which can be executed on the host computer is produced.

Abstract: A method for producing a computer-assisted real-time system that includes at least one processing unit. Data exchange between the processing unit and the environment or one or more additional processing units is synchronous or asynchronous. At least one real clock is allocated to the processing unit to correlate data exchange.
