Static stack-usage analysis for LEON3 and LEON4

StackAnalyzer for LEON3/LEON4 statically determines the worst-case stack usage of tasks in safety-critical applications written or generated in C, C++ or Ada and compiled to run on LEON3 or LEON4 processors.

Key features

Static analysis of binary files, exactly as they are executed in the final system.
Clear and precise information on the worst-case stack usage by tasks, procedures, basic blocks, and individual instructions.
Recursions, function pointers, inline assembly code, and library-function calls are all taken into account.
Automatic recognition of dead code.
Feature-rich GUI with graphical and textual views for analysis results, control flow, source code, assembly code, statistics, and more.
Command-line mode for easy integration into automated build processes.
Exceptionally fast analysis of complex real-world software.
Freely selectable entry points for the analysis, so you can focus on the worst-case path or other areas of interest, and speed up the analysis even further.
Seamless integration with other analysis tools from AbsInt — e.g. TimingProfiler for profiling the worst-case execution time.

Your benefits

StackAnalyzer lets you prevent stack overflow for all possible inputs and task executions under any circumstances — without wasting hardware resources.
StackAnalyzer requires no code instrumentation, no testing, no measuring, no modification of your system, no modification of your toolchain, and it will not be misled by potential flaws in debug information.
Using StackAnalyzer is essential in meeting current safety standards such as ISO 26262, DO-178B/C, IEC-61508, and EN-50128, where statically analyzing your stack usage is part of the architectural safety requirements.
