Track assignment
Beginner
Giving each planned wire its own lane within a stretch of the chip before the final drawing.
Novice
The step between global and detailed routing that puts the long straight pieces of each planned route onto specific tracks, so the detailed router starts from a sensible arrangement.
Expert
Usually greedy or graph-based, one strip of GCells (a panel) at a time. It is the first point where each wire’s neighbors are decided, so crosstalk-aware track assignment can keep sensitive nets apart or put shield wires beside them.
