# apr sim
Discrete-event simulation.
**Category**: Tools
This command surface previously shipped only as the standalone `simular` binary.
Its command enum lived in a `main.rs`, which is importable by nothing, so `apr`
had no route to it at all. `apr sim` and `simular` now call the same
`dispatch` function, so the two surfaces cannot drift.
## Synopsis
```text
apr sim <COMMAND>
```
## Subcommands
| `apr sim run` |
| `apr sim render` |
| `apr sim validate` |
| `apr sim verify` |
| `apr sim emc-check` |
| `apr sim emc-validate` |
| `apr sim list-emc` |
Every one of these is locked by `FALSIFY-CLI-006`: the list above and the built
binary are asserted to agree in both directions.
## Example
```bash
apr sim --help
```
## Full help
Run `apr sim --help` for the complete option list.
