What is proved¶
From benchmarks/motor_control/ld_latch_basic/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 |
!(Q && R) |
Unlatch is dominant within a scan: latched output Q and reset R never hold together. |

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.
