By introducing version 4.7 of its Universal Debug Engine (UDE) at this year’s Electronica trade show in Munich (hall A6, booth A16), PLS Programmierbare Logik & Systeme presents a debug, test, and system analysis tool that supports the internal debug functionalities of Infineon’s Aurix TC3xx multi-core micro-controller family. The multi-core SoCs of the second Aurix generation were specifically designed for electric and/or autonomous vehicles. Among other features, they offer a 300 % increase in processing power compared to current high-end automotive micro-controllers. For use as host controllers in gateway and telematics applications, the devices support a Gigabit Ethernet interface, up to 12 CAN FD channels according to ISO 11898-1, and a maximum of 24 LIN channels.

To let designers utilize this complexity and performance in practical applications, UDE 4.7 as a multi-core debugger enables controlling all Tricore processor cores from one single user interface. Depending on individual requirements, the cores can be controlled together, in groups or individually by traditional run-mode debugging, i.e. using breakpoints or single-stepping. In this mode, UDE enables all cores to be started and stopped almost synchronously using the devices’ on-chip debug logic. Debugging complex applications is further simplified by multi-core breakpoints that can be used in shared code. A multi-core breakpoint works all the time, regardless of which core is processing the code. Individually configurable views within UDE 4.7 additionally provide a better overview of multi-core applications.

For system-level analyses and to ensure functional safety, UDE 4.7 additionally provides trace-based tools leveraging the Aurix TC3xx family’s multi-core debug system (MCDS). MCDS is exclusively available in the so-called emulation devices (ED) of the TC39xx family. For instance, these tools can be used to trace code execution for post-mortem analyses or to provide profiling information for run-time optimizations. In addition, UDE 4.7 provides the necessary code coverage to prove adequate test coverage.

Tight coupling of third-party test tools to the UDE and comprehensive scripting are enabled by the high-performance automation interface of UDE 4.7, which is based on Microsoft’s Common Object Model (COM). UDE is also independent of any proprietary scripting languages.

Communication with Aurix TC3xx micro-controllers is based on the two Universal Access Devices (UAD2pro and UAD3+). Suitable adapters are available for the JTAG interface and Infineon’s proprietary DAP interface, with optional galvanic isolation for challenging environmental conditions. While UAD2 pro exclusively uses the on-chip trace memory for MCDS tracing, large amounts of trace data can be read from the chip at up to 22,5 Gbit/s using the UAD3+‘s Aurora interface for storage within the UAD3+ and subsequent processing and analysis by UDE 4.7. Up to 4 GiB of memory are available within UAD3+ for this purpose. The company shows its product at the Electronica 2016 fair in Munich, Germany.
