5
IAR C-SPY (1/2)

• IAR C-SPY Debugger is completely integrated into
  the IDE
• The C-SPY simulator is a fast and cost-effective
  tool for testing the program logic and simulating
  events
• Editor functions as source code browser allowing
  Edit-while-debug
• Breakpoints can be set directly in the source
  code
• Single stepping at function call level

6
IAR C-SPY (2/2)

• Optimized code can be debugged
• Profiling and code coverage
• Stack backtrace information available during
  program execution
• The open architecture allows C-SPY plug-ins for
  emulators and RTOS to be added
