Programmierbare Logik & Systeme (PLS) in Germany has launched a new version of its Universal Debug Engine (UDE) test and debug tool for multicore system-on-chip devices.
An intuitive user interface for debugging highly complex, next-generation multi-core system-on-chip designs in UDE 2021 adds a Python console with more optimised code coverage functions. To make analysis and debug of applications running on microcontrollers and processors with an ever-increasing number of cores more efficient, PLS is using a completely new layout framework in the UDE 2021 and a fully 64bit code base.
In contrast to the previous layout with fixed dock locations left, right, top and bottom and a central tab window in which windows were accessible via tabs, all windows in the debugger – which, for example, display the source code, internal states such as variables or registers, or also provide graphical visualizations – can now be arranged and grouped completely flexibly within the UDE user interface.
If required, the user can create a new dock location at any time or add a window as a new tab to an existing dock location. In addition, dock locations can also be created outside the main UDE window to accommodate single or multiple UDE windows. This allows for multi-monitor debug operation.
The Perspectives mode allows users to define multiple views within a debug session and switch between them to focus on a specific task. This is particularly useful for multi-core debugging, when the developer wants to analyze the behaviour of, for example, a core in detail. Perspectives can be created freely and debug windows can be placed and arranged in them without restriction.
The code coverage functions of UDE 2021, which provide developers with a metric for test quality, are also enhanced. The Universal Debug Engine (UDE) relies exclusively on trace information to calculate code coverage which means there is no need for instrumentation of the code under test. The entire code coverage analysis is therefore non-invasive and does not affect the
