The integration appeared in GLIWA T1 V3.6.1, released in August 2024, and supports PLS UAD2pro, UAD2next, and UAD3+ access devices.
What the UDE and T1.timing integration does
UDE provides the debug-interface communication channel between GLIWA T1.timing and a microcontroller in an electronic control unit (ECU). T1.timing needs a way to download timing information from the target and upload control information; through the controller’s debug unit, UDE supplies that connection. The UDE Object Model lets T1 collect timing information directly from real ECU hardware and connects the tools through software APIs.
This is an integration of the tools, not a replacement of T1.timing by UDE. UDE is the PLS debug and trace communication layer; T1.timing uses the data and its own analysis and control functions.
What engineers can do with the connected workflow
Profile execution and response time
T1.timing profiles core execution time (CET) and response time (RT), giving engineers timing information from the target ECU to analyze and optimize software behavior.

What changed in GLIWA T1 V3.6.1
Released in August 2024, T1 V3.6.1 added UDE to the available hardware-interface list in T1-HOST-SW. T1-HOST-SW automatically detects a connected UDE. Once connected, T1.timing can download timing information and write control data to the target.

The announcement identifies those access devices, but does not specify a complete list of supported microcontrollers or debug interfaces. Compatibility for a particular target should therefore be confirmed for the hardware and software configuration in use.
How the integrated workflow differs from the earlier transfer process
Before the integration, users could download trace data through PLS debugger infrastructure and import it into T1. That process required several manual steps and did not support all T1.timing features. The integrated connection reduces those transfer steps and makes a broader set of T1.timing analysis and debugging functions available in the workflow.
