Input activation port
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.
An integer defining the port number.
Properties : Type 'vec' of size 1.
always active: 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 :
