Behavior
One configured input remains in the compiled graph. Inactive producers are removed only when no live consumer still uses them.
Interface
| Name | Direction | Unit | Meaning |
|---|---|---|---|
in0 | input | 1 | Branch 0; real signal. |
in1 | input | 1 | Branch 1; real signal. |
out0 | output | 1 | Branch 0; real signal. |
Parameters
Defaults are initial model values. Select values for your own model and operating conditions.

Use in a workflow
Variant source — executable model
Selects an input branch before execution and removes unused inactive producers.
- Variant source: One configured input remains in the compiled graph. Inactive producers are removed only when no live consumer still uses them.
- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.
Connected concepts
Limits and interpretation
- Static zero-based selection among1–32 fixed typed branches. Shared live producers are preserved.
Reference basis
This compiler and software type contract is defined by the documented behavior and executable example; no external research result or full external API parity is claimed.
