Description

This block represent an activation input port. It must only be used inside a Xcos Super Block and be connected on an activation input in the subsystem.

This block is a event link from outside of a system into a sub-system. In a Super Block, the activation's input ports must be numbered from 1 to the total number of activation's input ports. You can set it with the Port number parameter.

Dialog box

• Port number

  An integer defining the port number.

  Properties : Type 'vec' of size 1.

Default properties

• always active: no

• direct-feedthrough: no

• zero-crossing: no

• mode: no

• number/sizes of activation inputs: 0

• number/sizes of activation outputs: 1

• continuous-time state: no

• discrete-time state: no

• object discrete-time state: no

• name of computational function: input

Example

In this example, we create a square wave generator with two inverted outputs by using a SUPER_f block with the contents shown in the following figure, where you can see the use of the CLKINV_f block as event input of the internal square wave generator.

The following figure shows the output of the bloc :
