Use Cases

• Timing measurement (e.g. max., min., average net execution times)
• Target-side timing verification (supervision)
• Automated timing tests
• Coverage of requirements, which arise from ISO 26262
• Implementation of the AUTOSAR Timing Extensions (TIMEX)
• Timing debugging: quickly detect and solve even awkward timing problems
• Exploration of free capacity, in oder to verify the timing effects of additional functionality before implementation, for example
• Investigation of dataflows and event chains and synchronization effects in multi-core projects
• Tracing of timing and functional problems without halting the target, particularly valuable in multi-core projects where it may be impractical to halt a single core

Extensions

T1.timing comes with two extension options. Add-on product T1.streaming provides the possibility to stream trace data continuously — over seconds, minutes, hours or even days. Add-on product T1.posix supports POSIX operating systems such as Linux or QNX.

T1 plug-ins

T1.timing comes with a modular concept and several plug-ins which are described in the following. Plug-ins can be easily enabled or disabled at compile-time using dedicated compiler switches such as T1_DISABLE_T1_CONT. To disable T1 altogether, it is sufficient to disable compiler switch T1_ENABLE which leaves the system in a state as of before the T1 integration.
