ABC will sometimes return negative frame numbers when proving by convergence, e.g. ``` engine_0: Proved output 1 in frame -698905656 (converged). engine_0: Proved output 4 in frame -698905656 (converged). ``` This change fixes these properties being missed and causing the engine status to return UNKNOWN due to `proved_count != len(proved)`.

That should be fixed in abc instead of working around it in SBY (or in addition to, the workaround itself is fine and shouldn't cause any additional issues even with it fixed in abc), can you share a project to reproduce this? |
