State of the art timing analysis...

...with industry-hardened methods and tools. T1 empowers and enables. T1 is the most frequently deployed timing tool in the automotive industry , being used for many years in hundreds of mass-production projects.
As a worldwide premiere, the ISO 26262 ASIL‑D certified T1-TARGET-SW allows safe instrumentation based timing analysis and timing supervision. In the car. In mass-production.

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.

The primary purpose of this tool is to allow engineers to view or edit "locked" logic blocks in older Siemens programming environments like .

: It does not defeat CPU-level hardware passwords or online access passwords.

While powerful for legacy systems, the tool has several hard boundaries:

The (often stylized as S7CanOpener) is a specialized third-party software utility designed to bypass the KNOW_HOW_PROTECT security feature in Siemens SIMATIC S7-300 and S7-400 PLC (Programmable Logic Controller) projects.

: Studying how specific standard library blocks or third-party functions were structured. Safety and Ethical Considerations

: It cannot unlock the newer "Block Privacy" protection introduced in Step 7 v5.5 or any TIA Portal (S7-1200/1500) security features.

: It removes the KNOW_HOW_PROTECT attribute from OB, FC, FB, and DB blocks.

: A system integrator is no longer in business, and the end-user needs to troubleshoot protected code.
