What is “T1 for POSIX”?

T1 version 3.2 introduced the support of POSIX operating systems through the add-on product T1.posix as an extension to T1.timing. Many operating systems for high-performance computing as well as the AUTOSAR AP standard are based on POSIX.

Key benefits of using T1 for the analysis of posix based systems

Live streaming of scheduling data from the target ECU
The T1-TARGET-SW traces at run-time and transmits the trace data via Ethernet to the
T1-HOST-SW. T1.timing in combination with T1.streaming and T1.posix offers the
following benefits:
  • The analysis and trace data visualization takes place simultaneously to streaming/recording
    data from the target ECU
  • Higher resource efficiency due to avoidance of costly file accesses
  • Traces of arbitrary lengths
T1 addresses the needs of the automotive
industry by supporting
  • Well-known timing results (e.g. CET, DT, RT, ...)
  • Visualization of AUTOSAR Deterministic Client Cycles
  • Combined and synchronized tracing of AUTOSAR CP/AP ECUs networks
  • Synchronized visualization and analysis of both system types in parallel and in the same view
  • Event chains (host-side)
  • Constraints (host-side)

Unique advantages of the T1 Timing suite compared to other solutions

  • Huge benefit in total cost of ownership because of single tooling for AUTOSAR CP/AP ECUs networks
  • No need to learn new tools since T1 is widely established in the automotive industry
  • One intuitive GUI covers all functionalities of T1.timing, T1.streaming and T1.posix
  • Flexible extension of T1 according to customer specific needs through dedicated engineering projects
  • Single point of contact for all questions around timing and resource analysis
