Behavior
Routes an integer mode to exactly one configured case flag or the final default flag, without fall-through. Outputs are held between accepted samples; numerical evaluation does not commit hidden state.
Interface
| Name | Direction | Unit | Meaning |
|---|---|---|---|
in0 | input | — | Case; i32 scalar. |
out0 | output | — | Case 0; bool scalar. |
out1 | output | — | Case 1; bool scalar. |
out2 | output | — | Case 2; bool scalar. |
out3 | output | — | Default; bool scalar. |
Parameters
Defaults are initial model values. Select values for your own model and operating conditions.
| Parameter | Unit | Default | Meaning and limits |
|---|---|---|---|
Sample periodsampleTimeS | s | 1 | Positive interval between accepted control samples. Outputs hold between these instants. Minimum 0 |
Case valuesparams[0] | — | 0 | Distinct 32-bit integers, one for each output; a default output is added. |
Case valuesparams[1] | — | 1 | Distinct 32-bit integers, one for each output; a default output is added. |
Case valuesparams[2] | — | 2 | Distinct 32-bit integers, one for each output; a default output is added. |
Equations and rules
case[i] = input = configuredCase[i]default = no configured case matches

Connected concepts
Limits and interpretation
- Control executes on an explicit sampled clock. Continuous states, history/delay kernels, residual equations, and event-source children are not supported.
- 1–31 distinct signed 32-bit cases and one default branch. There is no fall-through.
