# Statistics

The simulator collects execution statistics on the applications it executes.
The statistics summarize the various types of Hexagon processor events that
occurred while the application was running.

When an application terminates, the simulator writes the collected
statistics to a dedicated statistics file ([TCM modeling](https://docs.qualcomm.com/doc/80-N3040-23/topic/use-the-simulator.html#simulator-tcm-modeling)).
The symbols that appear in the file define the types of statistics collected.

Because the types of execution events vary across the Hexagon
processors, different types of statistics are collected for each
processor version. For more information, see the
*Qualcomm Hexagon Programmer’s Reference Manual*.
