Model of a Set-reset Flip Flop
Extends from Interfaces.LogicalBlock2x2 (partial interface of a generic 2x2 logical block).
Information
Description
Model of a Set Reset Flip Flop.
The inputs and outputs follows
| Name | Description |
|---|---|
| u1 | Set |
| u2 | Reset |
| y1 | Q |
| y2 | not Q |
Behaviour of the FlipFlop, at each time step Ts the inputs are read and the new output Q
is computed starting from the S and R value as well the old value of the output
QOLD.
| Set | Reset | Q |
|---|---|---|
| 0 | 0 | QOLD |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | not QOLD |
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | Ts (from LogicalBlock2x2) | 0.1 | sampling time |
| Boolean | q_start | false | Output initial value |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Blocks.Interfaces.BooleanInput | u1 (from LogicalBlock2x2) | input | |
| Modelica.Blocks.Interfaces.BooleanOutput | y1 (from LogicalBlock2x2) | output | |
| Modelica.Blocks.Interfaces.BooleanInput | u2 (from LogicalBlock2x2) | input | |
| Modelica.Blocks.Interfaces.BooleanOutput | y2 (from LogicalBlock2x2) | output |
