 Trace view is a view in which you can see history of stepped instructions. This lets you examine the details of each instruction stepped when you are stepping manually or [tracing](../../introduction/ConditionalTracing.md) automatically, or view a trace history previously saved. This functionality must be enabled explicitly from trace view or [CPU view](CPU.rst). It features saving all the instructions, registers and memory accesses during a trace.

 ## Start Run Trace
 
 To enable trace logging into trace view, you first enable it via "**Start Run Trace**" menu. It will pop up a dialog allowing you to save the recorded instructions into a file. The default location of this file is in the database directory.
