Many users are utilizing Scilab/Xcos to simulate complex and large systems. There simulation time becomes an issue. Knowing execution time of blocks becomes a key capability to optimize the simulation design to achieve better performance.
As a benchmark, MATLAB/Simulink has a profiler feature which analyses and presents an execution time hierarchy of a model. By using MATLAB/Simulink Profiler, users can evaluate and improve performance of their simulations. This proposal defines a similar profiling capability for Scilab/Xcos.
