Convergence Sink Above

Gallery / Merge & Convergence

An input section sits above the shared sink it feeds, while its line is declared last. The sink's entry bundle is slotted by feeder approach (the feeder whose source sits highest takes the topmost lane) rather than by declaration order, so the line runs straight into the port instead of dropping down across its bundle-mate.
