An EDA software feature that calculates and draws copper traces to connect netlist nodes automatically. Users define rules for trace width, clearance, and layer usage, and the algorithm attempts to complete all connections. While useful for simple boards or non-critical signals, it often struggles with complex impedance control, analog signals, and optimal component placement.
Heard on the job
I ran the autorouter on the digital section just to see if the placement was viable before doing it by hand.
Insider tip
Veteran designers rarely use autorouters for an entire board, preferring to route critical signals manually and only using the tool for bulk connections like memory buses.
