Xor

Logical xor of inputs

Modelica Standard Library

Description

Compute the exclusive-or of the inputs. Two definitions of exclusive-or are supported:

1.	If the Compute parity parameter is $false$ (the default), the output is $true$ if exactly one input is $true$ , otherwise the output is $false$ .

2.	If the Compute parity parameter is $true$ , the output is $true$ if an even number of inputs are $true$ , otherwise the output is $false$ .

The Use vector boolean parameter selects the type of inputs.

•	If $false$ (the default), the block has two boolean inputs, $u1$ and $u2$ .

•	If $true$ , the block has a single boolean vector input, $u$ , and the Signal size parameter sets the dimension of $u$ . Signal size must be greater than $1$ .

Connections

Name	Description	Modelica ID
$u1$	Boolean input signal 1	u1
$u2$	Boolean input signal 2	u2
$y$	Boolean output signal	y
$u$	Boolean input vector	u

Parameters

Name	Default	Units	Description	Modelica ID
Use vector	$false$		True (checked) means use a single boolean vector input; otherwise use two scalar boolean inputs	useVector
Signal size	$2$		Dimension of the vector input signal (n>1)	signalSize
Compute parity	$false$		True (checked) means return $true$ if and only if an even number of inputs are $true$ ; otherwise, return $true$ if and only if exactly one input is $true$	computeParity
