User Guide¶
Design¶
This is the main panel. It contains the blocks and the wires.
Pan & Zoom¶
Pan is performed using the Ctrl + mouse left button or mouse right button over the background. Zoom is performed using mouse wheel.
Select¶
Block selection is performed with the mouse left button. Blocks can be selected/unselected individually using Shift+left-click. In addition, several blocks can be selected by a selection box. A selection is canceled when the background is left-clicked.
Move blocks¶
Any block or blocks selection can be moved in the design using the mouse left button over the block or the selection. Also a blocks selection can be moved with the arrow keys.
Resize text blocks¶
Memory, Code, and Information blocks can be resized with the resize tool in the bottom-right corner of the block.
Block examination¶
Non-basic blocks can be read only examined by double clicking the block using the mouse left button. This is a recursive action. In order to go back, click on the < back link or press the back key.
During the examination, pan, zoom and code navigation are enabled. Also the ‘Fit content’ action.
Note
The examination path is stored in the breadcrumbs. This allows to go back to any previous block.
