Code Execution Profiling

View and analyze execution profiles of code sections

Use code execution profiling to:

Establish whether the generated code meets real-time requirements of your target hardware.
Determine code sections that require performance improvements.

You can configure software-in-the-loop (SIL) and processor-in-the-loop (PIL) simulations to produce execution-time metrics for tasks and functions in your generated code. Use the code execution report or Simulation Data Inspector to analyze execution times.
