Abstract
Systems and methods for synchronizing programs for simulation of a technical system. The programs including a first simulation program and a second simulation program. The first simulation program simulates the kinematics of the technical system and the second simulation program simulates a control of the operation of the technical system. The first simulation program outputs values of a first variable at first-time points between first-time intervals according to a first frequency in virtual simulated time and the second simulation program outputs values of a second variable at second time points between second time intervals according to a second frequency in virtual simulated time, the first frequency being lower than the second frequency. Values of the first variable at second time points between two successive first-time points are determined based on an approximation, where the second simulation program uses the approximated values in order to determine values of the second variable at second time points between the two successive first-time points. An error is determined based on the absolute value of the difference between a first integral value as seen from the first simulation program and a second integral value as seen from the second simulation program. A warning is output by a user interface in case that the error exceeds a predetermined threshold.
