TRACE EXTENSION FOR NIOS-II


 

NIOS-II Trace Features For Advanced Debugging


Program Flow Trace

Data Trace

Timestamp

Trace Filter and Trigger
  • 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
Trace-based Debugging (CTS)
  • 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
SmartTrace
  • Fills in missing code
  • Direct branch reconstruction
  • Indirect branch reconstuction with CTS
  • Memory and Register values from CTS
Energy Profiling
  • Find the program part causing the highest energy consumption
  • Locate unexpected power peaks
  • Check if power-saving modes are used efficiently
  • Current and voltage measurement with TRACE32 Mixed Signal Probe or TRACE32 Analog Probe
  • Time correlation with TRACE32 trace tools PowerTrace, CombiProbe, MicroTrace
  • Energy statistics on function and task level
RTOS
RTOS Support
 

NIOS-II Trace Features For Runtime Analysis


Trace-based Profiling
