StackAnalyzer automatically determines the worst-case stack usage of the tasks in your appli­cation. It lets you find any stack overflows, or formally prove the absence thereof.

Safe upper bounds on maximal stack: no more stack overflows!


  • Precise, clear, and detailed information on user-stack usage and system-stack usage by application tasks.
  • Freely selectable entry points for the analysis. You can easily focus on any code parts of particular interest to you.
  • Control-flow reconstruction directly from binary code. Potential flaws in the debug information will not confuse StackAnalyzer.
  • Fully integrated, feature-rich graphical and textual viewers for control flow, analysis results, source code, assembly code, DWARF debug info, symbol tables, configuration files, and more.
  • Customizable XML reports for documentation and certification.
  • ValueAnalyzer add-on for static analysis of register and memory cells, memory accesses and function calls.
  • Seamless integration with other analysis tools from AbsInt (e.g. aiT for worst-case execution time analysis).
  • Batch mode for easy integration with other tools and into automated build processes.
  • Qualification Support Kits for ISO 26262, DO-178B/C, and other safety standards.

Your benefits

StackAnalyzer reduces the development effort and helps prevent runtime errors due to stack overflow.

StackAnalyzer calculates the stack usage automatically. No testing or measuring required. The analysis results are valid for all inputs and any task execution.

StackAnalyzer directly analyzes binary executables, exactly as they are executed in the final system.

Using StackAnalyzer is essential in meeting current safety standards such as ISO 26262, DO-178B/C, IEC-61508, and EN-50128, where statically analyzing the stack usage is part of the architec­tural safety requirements.

Qualification support

Your usage of StackAnalyzer can be qualified according to ISO 26262, DO-178B/C, and other safety standards. We offer special Qualification Support Kits that simplify and automate the qualification process. These Kits have been successfully used by many customers in their qualification processes, notably in the avionics and automotive industries.

StackAnalyzer is also available as an integral part of the SCADE development envi­ron­ment, which is DO-178B and DO-178C qualified up to level A for Military and Aerospace Industries, IEC 61508 certified at SIL 3 by TÜV for Heavy Equipment and Energy, and EN 50128 certified at SIL 4 by TÜV for Rail Transportation. Within SCADE, you’ll find the tool under the name “Timing and Stack Optimizer”.
