• Imagine running backward to the origin of a difficult bug. TimeMachine enables you to debug both forward and backward in time, making it easier to solve even the hardest bugs.
• Imagine making your program run faster than you ever thought possible. The PathAnalyzer—one component of TimeMachine—provides a unique display of your program's execution history that lets you quickly and easily find previously unknown bottlenecks in your software.
• Imagine undoing a single step in your debugger. Step backward into functions that you've already stepped over, whether intentionally or by accident, to accelerate your debugging.
• Imagine leveraging gigabytes of execution history to verify that your program has been fully tested. TimeMachine integrates with the MULTI Profiler to enable full coverage testing through MULTI's detailed coverage reports.
• Now imagine any other problem. Using TimeMachine's open architecture, you can write custom analysis tools that solve problems unique to the requirements of your software development project.

• Development proceeds more quickly when using innovative TimeMachine debugging capabilities to help find and fix bugs faster
• Integration flows smoothly when powerful TimeMachine performance analysis tools are put to work uncovering system bottlenecks
• Testing is more thorough when test code is verified using advanced TimeMachine code coverage tools

• Viewing register and memory values at any point in the trace data
• Finding specific trace data points using complex execution and data breakpoints
• Examining RTOS data structures to quickly debug task interaction bugs
• Debugging virtual memory applications, such as those in applications running under the INTEGRITY® RTOS

Besides the TimeMachine Debugger, the TimeMachine Suite offers tools that make debugging applications faster and more efficient, including:

• PathAnalyzer: By providing a view of an application’s call stack over time, the PathAnalyzer helps identify bugs and inefficiencies in code. With the PathAnalyzer, developers can quickly determine where the code diverts from the expected path as well as track down anomalous bugs caused by events such as unexpected interrupts or other random glitches.
• EventAnalyzer: The TimeMachine Suite is integrated with the MULTI EventAnalyzer, which displays a view of operating system events over time. This display helps track down bad interactions such as deadlocks between various tasks that cause undesirable behavior in your system. TimeMachine supports all Green Hills Software operating systems: the INTEGRITY RTOS, the velOSity kernel, and the µ-velOSity microkernel.
   

• Easily measure important system metrics such as interrupt latency, context switch time, and boot time with great accuracy and precision
• Perform detailed performance analysis over long periods of time
• Quickly debug a performance problem once it’s located

Along with the PathAnalyzer and EventAnalyzer, the TimeMachine Suite integrates the patented MULTI Profiler to offer the following capabilities to help you more easily identify performance problems in embedded code:

• 	By providing a graphical display of all operating system events, the MULTI EventAnalyzer tool is helpful both during debugging—to help track down bad interactions—as well as during optimization when it can quickly show which operations take the most time.

  PathAnalyzer: By making it obvious which functions take the most time, the PathAnalyzer is the ideal tool for pinpointing performance bottlenecks. With its intuitive interface, the PathAnalyzer can offer a unique level of detail to make performance optimization easier and more productive.
  
   
• EventAnalyzer: The EventAnalyzer provides a graphical display of operating system events such as kernel service calls, interrupts, exceptions, and context switches. With this information, it’s quickly apparent what operations take the most time and where optimization efforts should be focused.
  
   
• MULTI Profiler: The integration of the TimeMachine Suite with the MULTI Profiler helps to quickly determine how much time an application spends in various places. The MULTI Profiler can create reports with valuable and revealing information about blocks, source lines, and functions to make it easier to find and fix performance problems.

And, since all of these tools are integrated with the TimeMachine debugger, once you’ve located a performance problem, you can easily open the TimeMachine debugger to find the source of the problem.

• MULTI Profiler: The MULTI Profiler offers code coverage reports that make it easy to determine what blocks and source lines have not been executed. Using this information, you can augment your test suite to include tests that exercise all of your code.
   

The MULTI Profiler tool helps both during optimization as well as
testing by providing code coverage reports that make apparent
which blocks and source lines have not been executed.
