What is proved¶
From benchmarks/hvac/ld_tof_hold/props.yaml. What each kind claims, and what it becomes on either route, is on The properties we prove.
| id | kind | claim | requirement |
|---|---|---|---|
P1 |
invariant |
!Pir || Light |
While the PIR sees motion the lamp must be lit; the off-delay only extends that, it never shortens it. |

Recorded runs¶
A task can carry two routes. ld is ESBMC's ladder front end reading the program directly. via C is the same solver reached through Beremiz and MatIEC, which is the only route that reaches ST, IL, FBD and SFC; see How ESBMC-PLC works.
No ESBMC run is recorded against this task yet. The lessons carry the recorded runs; see Reproducing to make your own.
