Automated Performance Optimization

Analyze model for inefficient conditions and settings, automatically improve simulation speed using Performance Advisor

Performance Advisor can check your model for conditions and settings that can slow down simulation speed. It can recommend modeling optimizations, implement them automatically, and run simulations in accelerator mode for you. For more information, see Improve Simulation Performance Using Performance Advisor.

Featured Examples

Use Hardware Acceleration to Speed Up Simulation for Object Detection

Use hardware acceleration to speed up a Simulink® model simulation for object detection. You can use Performance Advisor to compare simulation speeds and select an appropriate level for hardware acceleration. Hardware acceleration is achieved by leveraging single instruction, multiple data (SIMD) in simulation targets. All processors that support Simulink simulation have SIMD instructions. For more information, see Hardware acceleration and SIMD Code Generation (DSP System Toolbox).
