This package contains basic mathematical operations on Boolean signals.
The new features are:
Extends from Modelica.Icons.Package (Icon for standard packages).
| Name | Description |
|---|---|
And | Logical 'and': y = u[1] and u[2] and ... and u[nu] |
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)) |
FallingEdge | Output y is true, if the input u has a falling edge, otherwise it is false (y = edge(not u)) |
MultiSwitch | Set Boolean expression that is associated with the first active input signal |
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 |
OnDelay | Delay a rising edge of the input, but do not delay a falling edge. |
Or | Logical 'or': y = u[1] or u[2] or ... or u[nu] |
RisingEdge | Output y is true, if the input u has a rising edge, otherwise it is false (y = edge(u)) |
Xor | Logical 'xor': y = oneTrue(u) (y is true, if exactly one element of u is true, otherwise it is false) |
The block has a vector of Boolean input signals u[nu] and a vector of (time varying) Boolean expressions expr[:]. The output signal y is set to expr[i], if i is the first element in the input vector u that is true. If all input signals are false, y is set to parameter "y_default" or the previous value of y is kept if parameter use_pre_as_default = true:
// Conceptual equation (not valid Modelica)
i = 'first element of u[:] that is true';
y = if i==0 then (if use_pre_as_default then pre(y)
else y_default)
else expr[i];
The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.BooleanNetwork1.
| Type | Name | Default | Description |
|---|---|---|---|
Boolean | use_pre_as_default | true | set true to hold last value as default (y_default = pre(y)) |
Boolean | y_default | false | Default value of output y if all u[i] = false |
Integer | nu | 0 | Number of input connections |
| Type | Name | Description |
|---|---|---|
input BooleanVectorInput | u[nu] | Set y = expr[i], if u[i] = true |
output BooleanOutput | y | Output depending on expression |
The output is true if all inputs are true, otherwise the output is false.
The input connector is a vector of Boolean input signals. When a connection line is drawn, the dimension of the input vector is enlarged by one and the connection is automatically connected to this new free index (thanks to the connectorSizing annotation).
The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.BooleanNetwork1.
If no connection to the input connector "u" is present, the output is set to false: y=false.
