# addConnection

The addConnection API is used to link the output of one component to the input of another within an SSP model. Connections define the signal flow between components, ensuring that data is transmitted correctly during simulation.

Connections are defined using source and target references:

  - Source: Specifies the output variable of a component.

  - Target: Specifies the input variable of another component.

Syntax:

    addConnection(source: CRef, target: CRef)

Parameters:

  - `source` (CRef): Reference to the output variable of the source component.

  - `target` (CRef): Reference to the input variable of the target component.

Example:

    from OMSimulator import SSP, CRef, Settings

    model = SSP()
    model.addResource('../resources/Modelica.Blocks.Math.Add.fmu', new_name='resources/Add.fmu')
    model.addResource('../resources/Modelica.Blocks.Math.Gain.fmu', new_name='resources/Gain.fmu')

    model.addComponent(CRef('default', 'Add1'), 'resources/Add.fmu')
    model.addComponent(CRef('default', 'Gain1'), 'resources/Gain.fmu')
    ## add a connection from Gain1.y to Add1.u1
    model.addConnection(CRef('default', 'Gain1', 'y'), CRef('default', 'Add1', 'u1'))
    ## list the components in the model and connections
    model.list()
