Use blocks from the Sources library to provide input signals for simulation.
Generate signals in your model using blocks such as the Sine Wave block and the Constant block.
Load signal data from the workspace or a file using blocks such as the From Workspace block, the From File block, and the From Spreadsheet block.
Create and edit signals using blocks such as the Signal Editor block.
