NIOS II Trace

Program Flow Trace

Data Trace

Timestamp

• Sample only the specified event
• Sample the complete program flow and the specified data event
• Switch the sampling to the trace buffer on/off after a specified event occurred

• Allows re-debuggging of a traced program section
• Provides forward and backward debugging capabilities
• High-level language trace display including all local variables
• Timing and function nesting display
• Has the ability to fill most trace gaps caused by the limited bandwidth of trace port

• Fills in missing code
• Direct branch reconstruction
• Indirect branch reconstuction with CTS
• Memory and Register values from CTS

• Realtime measurement of 3 current and 4 voltage lines
• Realtime trigger on current, voltage and power
• Time correlation with other TRACE32 tracetools
• Energy statistics on function and task level
• Fully integrated in the TRACE32 user interface
