Keyboard Shortcuts

Installation and Usage

The revedaPlot plugin is automatically loaded when Revolution EDA starts. A valid license is required. Access plotting features through:

1. Automatic Launch: Plots appear automatically when simulation completes via Results → Plot Results
2. Manual Launch: Open data files directly with File → Open Data File (Ctrl+O) supporting .raw and .prn formats
3. Back Annotation: Annotate simulation values onto schematics via Results → Back Annotate
4. Export Functions: Save plots as PNG or JPEG for documentation

License
