Input activation port

Block Screenshot


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


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 :
