.Modelica.Blocks.MathBoolean

Information

This package contains basic mathematical operations on Boolean signals.

The new features are:

• If useful, blocks may have an arbitrary number of inputs (e.g., "And" block with 2,3,4,... Boolean inputs). This is based on the "connectorSizing" annotation which allows a tool to conveniently handle vectors of connectors.
• The blocks are smaller in size, so that the diagram area is better utilized for trivial blocks such as "And" or "Or".

Contents

Name	Description
MultiSwitch	Set Boolean expression that is associated with the first active input signal
And	Logical 'and': y = u[1] and u[2] and ... and u[nu]
Or	Logical 'or': y = u[1] or u[2] or ... or u[nu]
Xor	Logical 'xor': y = oneTrue(u) (y is true, if exactly one element of u is true, otherwise it is false)
Nand	Logical 'nand': y = not ( u[1] and u[2] and ... and u[nu] )
Nor	Logical 'nor': y = not ( u[1] or u[2] or ... or u[nu] )
Not	Logical 'not': y = not u
RisingEdge	Output y is true, if the input u has a rising edge, otherwise it is false (y = edge(u))
FallingEdge	Output y is true, if the input u has a falling edge, otherwise it is false (y = edge(not u))
ChangingEdge	Output y is true, if the input u has either a rising or a falling edge and otherwise it is false (y=change(u))
OnDelay	Delay a rising edge of the input, but do not delay a falling edge.
