State of the art timing analysis

State of the art timing analysis
with industry-hardened methods and tools.
...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.
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.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.
"Skyrim Special Edition 1.6.640 Verified" signifies a stable, officially supported build of the game that runs excellently on the Steam Deck. It is a milestone update that proved Bethesda could successfully bring the massive RPG to handheld Linux-based hardware.
However, for PC modding enthusiasts, this version is often viewed with caution. It serves as a reminder of the conflict between official updates (which break mod dependencies) and the community's need for version stability.
To ensure the game runs without crashing on 1.6.640, the following mods act as the foundation for any verified build:
To ensure you are on the correct, verified build:
If you are aiming to replicate a stable, "verified" experience on this version, here are the technical specifications and requirements:
If Steam has auto-updated past 16640, you can revert using the Steam Console method:
⚠️ Note: Permanently staying on 16640 requires blocking Steam’s automatic updates for Skyrim SE (e.g., setting
appmanifest_489830.acfto read-only or using offline mode).
Because 1.6.640 is verified to work with the "Best of Both Worlds" patcher (a tool that lets you keep Anniversary Edition content but use the 1.5.97 .exe), it has become the nexus of the downgrading community. Many mod lists are built specifically for 1.6.640, refusing to update further.
Game: The Elder Scrolls V: Skyrim Special Edition
Build ID: 16640
Status: Verified Stable Build
Platform: PC (Steam / GOG equivalent)
Commonly Associated With: Pre-Anniversary Edition update, pre-1.6.x “Anniversary Update” breaking changes

| Target Interface | Comment |
|---|---|
| CAN | Low bandwidth requirement: typically one CAN message every 1 to 10ms. The bandwidth consumed by T1 is scalable and strictly deterministic. |
| CAN FD | Low bandwidth requirement: typically one CAN message every 1 to 10ms. The bandwidth consumed by T1 is scalable and strictly deterministic. |
| Diagnostic Interface | The diagnostic interface supports ISO14229 (UDS) as well as ISO14230, both via CAN with transportation protocol ISO15765-2 (addressing modes 'normal' and 'extended'). The T1-HOST-SW connects to the Diagnostic Interface using CAN. |
| Ethernet (IP:TCP, UDP) | TCP and UDP can be used, IP-address and port can be configured. |
| FlexRay | FlexRay is supported via the diagnostic interface and a CAN bridge. |
| Serial Line | Serial communication (e.g. RS232) is often used if no other communication interfaces are present. On the PC side, an USB-to-serial adapter is necessary. |
| JTAG/DAP | Interfaces exist to well-known debug environments such as Lauterbach TRACE32, iSYSTEM winIDEA and PLS UDE. The T1 JTAG interface requires an external debugger to be connected and, for data transfer, the target is halted. TriCore processors use DAP instead of JTAG. |
