PreRoutGNN reports strong pre-routing slack prediction performance. Topological DAG-GNNs structurally match timing propagation better than synchronous fixed-depth GNNs. The paper treats its timing equations as simplified and not a complete industrial STA model. Arrival time uses a max-plus recurrence, required arrival time uses a min-plus dual, and slack is their difference. Static timing is presented as the clearest match for asynchronous DAG message passing.
