Generic Timer Module (GTM) Debug and Trace Support

The Universal Debug Engine provides debug and trace support for the Bosch Generic Timer Module (GTM).

The GTM is a powerful and sophisticated timer module ensuring accurate multi-input data acquisition and multi-output signal generation in automotive powertrain and active safety applications or in industrial closed-loop applications.

The GTM is an IP block from Bosch and implemented by various semiconductor vendors in their multi-core microcontroller families, e.g.:

TriCore™ AURIX™ from Infineon
Stellar from STMicroelectronics
Power Architecture™ based MPC57xx from NXP
Power Architecture™ based SPC5 from STMicroelectronics

Multi Channel Sequencers (MCS)
- RISC-like programmable cores
- Eight independent tasks per MCS
Time Base Unit (TBU) to provide time bases to submodules
Advanced Routing Unit (ARU) for routing data between submodules
Input/output modules (TIM, TOM, ATOM, DTM) for
- Sampling external signals
- Generating output signals to drive outside world
Interrupt Concentrator to bundle GTM interrupts and reduce number of interrupt lines to the outside SoC system

UDE - Universal Debug Engine - Support for Generic Timer Module (GTM)

The Universal Debug Engine provides debug and trace support for GTM implementations integrated in various multi-core microcontroller families.

Debugging and testing for the GTM is fundamentally different from traditional debugging for microcontrollers. Due to the specific hardware characteristics and the real-time characteristics of the applications, stop-mode debugging is not possible or only possible to a limited extent for the GTM. Therefore, trace is crucial for the development of GTM applications. UDE addresses this by providing extensive trace support for devices with GTM.
