In VLSI design, a fly line is a conductive line that runs parallel to another line, but is not electrically connected to it. Fly lines are used to route signals between different parts of a circuit.
Fly lines are conductors on a substrate that are used to interconnect different device regions. They provide the path for currents to flow between devices and also act as a network of capacitors that can store charge.
Fly lines are conductive lines in a VLSI circuit that are used to interconnect different circuit elements. They are typically made of aluminum or copper and are insulated with a dielectric material.
