When a trace has been captured, the debugger extracts the information from the
trace stream and decompresses it to provide a full disassembly, with symbols, of the
The left-hand column of the chart shows the percentages of the total trace for
each function. For example, if a total of 1000 instructions are executed and 300 of
these instructions are associated with
then this function is displayed with 30%.
In the navigational timeline, the color coding is a heat map showing the
executed instructions and the number of instructions each function executes in each
timeline. The darker red color shows more instructions and the lighter yellow color
shows fewer instructions. At a scale of 1:1 however, the color scheme changes to
display memory access instructions as a darker red color, branch instructions as a
medium orange color, and all the other instructions as a lighter green color.

The Trace view might not be visible by default. To add this view:
Ensure that you are in the DS-5 Debug perspective.
The Trace view navigation chart
contains several tabs:
Trace tab shows the graphical timeline and
Capture Device tab gives information about the trace
capture device and the trace buffer, and allows you to configure the trace
Source tab gives information about the trace
Ranges tab allows you to limit the trace capture to
a specific address range.
The Trace tab also shows:
- Buffer Size
Size of the trace buffer to store trace records. This is determined by the
trace capture device. The trace records can be instruction records or
- Buffer Used
Amount of the trace buffer that is already used for trace records.
- Records in Page
The total number of instruction records and non-instruction records in
the current Trace view.
- Records Visible
The number of trace records visible in the disassembly area of the
