Route under the project's rules and net classes. By default (no nets, no router, none of the single-route options below) it runs the full route pipeline Koppar benchmarks: the learned router on the whole board racing the negotiated router on a copy (the board with fewer open items, then fewer DRC errors, goes on), repair rounds on what stays open, the local finish, copper finishing (0/45/90 runs) and one repair round after it, inside one wall-clock cap: time_budget_s is that cap (default 1200, up to 1500), so the job runs up to about 20 minutes: follow it with get_board_job. The result gives the final unconnected items and DRC errors and a pipeline summary: the counts after the route and after each finish, which arm won, whether the copper finishing was kept. preserve_existing unset keeps the copper of a board that has tracks or vias (the negotiated arm then does not run: it routes from scratch) and routes a board without any from scratch; false routes every net again. nets, router, or any single-route option (pours, rule overrides, via_cost, grid_mm, negotiation_rounds, ml_options, seed_existing, fewest_vias, pairs_first, class_vias) runs ONE route with that router instead, for expert control: nets limits it to those nets; preserve_existing (default true) keeps every track and via already on the board and routes only what is still open. pours: "keep" (the default when the board has zones) keeps the board's zones and routes every net as tracks; "engine" plans a GND pour and fans GND to it by via. Rule overrides apply to this run only. via_cost raises the price of a via in the local router (its default is 2), for fewer vias at some completion cost; the learned router takes its via discipline in ml_options. A single route takes time_budget_s (default 120, up to 900).
