aiT for C16x/ST10 statically computes tight upper bounds for the worst-case execution time of tasks in safety-critical applications written or generated in C or C++ and compiled to run on C16x processors from Infineon or STMicroelectronics.
Key benefits
- The static analysis guarantees that the computed WCET bounds are valid for all possible inputs, all possible cache and pipeline states, and each task execution under any circumstances. With that, extensive timing testing is a thing of the past.
- aiT directly analyzes binary executables, exactly as they are executed in the final system. This requires no modification of your system’s operational behavior or performance, and no modification of your toolchain.
- aiT-computed bounds are extremely tight and thus reflect the actual performance of your system. Deadline adherence is ensured without wasting hardware resources.
- aiT lets you easily save and compare the analysis results before and after making changes to your system, such that their effect on the worst-case timing can be understood immediately and completely.
- Using aiT is essential in meeting current safety standards such as ISO 26262 and DO-178B/C, where static WCET analysis is part of the architectural safety requirements.
