impulse for Visual Studio Code

impulse is an event and waveform visualization and analysis workbench (simulation, traces, logs) which helps engineers to comfortably understand and debug complex semiconductor and multi-core software systems.

This vscode extension is an early beta (non-productive) version with basic features.

THIS BETA SOFTWARE IS BELIEVED TO CONTAIN DEFECTS. USER IS ADVISED TO SAFEGUARD IMPORTANT DATA, TO USE CAUTION AND NOT TO RELY IN ANY WAY ON THE CORRECT FUNCTIONING OR PERFORMANCE OF THE SOFTWARE.

Quick Start

• Select a file to view.
• Use the context menus 'Open with' and select the impulse Viewer (You may select the impulse Viewer as the default option at this point).
• On activation, it may take a while (a few secs) to load the backend java server. The OS may ask you for approval.
• Create a new view.
• Open the 'Samples panel' to examine the signal details.
• Have fun !
