Library Browser Shows all blocks available in Simulink, sorted by folders such as ‘Math
Operations’ or ‘Signal Routing’. There is a search bar on the top left. Drag
blocks from the library straight onto your model canvas.
Quick Search Directly search for blocks by single clicking on the background of your
model and typing in a search term. Select a block from the search results to
quickly add it to your model.
Automatic Block Input Box When adding a block to a model for the first time, the most common
parameter will often pop up automatically for a value to be specified.
e.g. If you add a Gain Block it will ask you to specify the gain value. Interacting with this can save time opening the Block Parameters menu Positioning Blocks
Blocks can be moved by simply clicking and dragging.
Connect blocks by clicking output of one block and dragging it to an input of another block.
Once a signal connects two blocks, it can be clicked and dragged to be repositioned.
To create a branch from an existing signal, hold ctrl while clicking and dragging.
Blocks can be rotated/flipped for better positioning: Right click block, select “Rotate & Flip”.
