Sources

Provide inputs for simulation using blocks that define and generate signals or load signal data

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.
