aiT WCET Analyzer for C28x 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 TMS320F28x processors.
Your benefits
- The static analysis guarantees that the computed WCET bounds hold for all possible inputs, all possible cache and pipeline states, each task execution under any circumstances. No testing or measuring required.
- aiT directly analyzes binary executables, exactly as they are executed in the final system. It 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.

Timing profiling from day one
If you haven’t yet settled for a specific derivate — or if the final decision is not yours to make —, you can nonetheless benefit from static analysis to develop your application in a timing-conscious way, from day one.
For this, you can use the fully-integrated TimingProfiler. It will help you identify application parts that will cause unsatisfactory execution times regardless of the specific make of C28x that you end up using.
Once the hardware has been decided on, you can then easily switch from TimingProfiler to aiT, within the same GUI, keeping all your settings and annotations, and without having to install anything.
