Abstract
Example implementations involve systems and methods which can involve storing interface (I/F) communication activity records of a plurality of simulation engines during execution of a co-simulation, and for a subsequent execution of the co-simulation, replacing one or more of the plurality of simulation engines with a simulation engine repeater configured to reproduce I/F communication activity from the stored I/F communication activity records corresponding to the replaced one or more of the plurality of simulation engines during the subsequent execution of the co-simulation and to log a real time consumed for execution of the reproduced I/F communication activity in the subsequent execution and a simulation time consumed for execution of the reproduced I/F communication activity for each simulation step, the real time determined based on a real time difference between a start of each simulation step and completion of synchronization with a co-simulator bus at an end of each simulation step.
