Program step visualization implementation method and system in a vehicle simulation test process

A program step visualization implementation system in a C code-based vehicle simulation test process, comprising a computer device, wherein the computer device further comprises:

• a setting module, configured to respectively set a mark parameter of an activation state and a non-activation state corresponding to a corresponding execution state for each execution box in a C code-based graphics program;
• a marking module, configured to:
• when the execution state of the execution box changes, change a display mark of the execution box into an activation state mark corresponding to a new execution state;
• and when a current execution state of the execution box remains unchanged for a preset time period, change the display mark of the execution box from the activation state mark into a non-activation state mark.
