Using Simulink

Connecting Blocks

Simulink block diagrams use lines to represent pathways for signals among blocks in a model (see Annotating Diagrams for information on signals). Simulink can connect blocks for you or you can connect the blocks yourself by drawing lines from their output ports to their input ports.

Automatically Connecting Blocks

You can command Simulink to connect blocks automatically. This eliminates the need for you to draw the connecting lines yourself. When connecting blocks, Simulink routes lines around intervening blocks to avoid cluttering the diagram.

Connecting Two Blocks

To autoconnect two blocks:

1. Select the source block.
   
   
2. Hold down Ctrl and left-click the destination block.

1. Simulink connects the source block to the destination block, routing the line around intervening blocks if necessary.
   
   

When connecting two blocks, Simulink draws as many connections as possible between the two blocks as illustrated in the following example.

Connecting Groups of Blocks

Simulink can connect a group of source blocks to a destination block or a source block to a group of destination blocks.

To connect a group of source blocks to a destination block:

1. Select the source blocks.
   
   
2. Hold down Ctrl and left-click the destination block.
   
   

To connect a source block to a group of destination blocks:

1. Select the destination blocks.
   
   
2. Hold down Ctrl and left-click the source block.
