A stabilizer for a vehicle with suspension springs having a rigid member with a face and back. The apparatus includes first means adapted to determine the difference between the first analog value and a second analog value of the input signal at a second time instant successive to the first time instant. In one embodiment, the coarse placer can also be used to automatically size cells, insert and size buffers, and aid in timing driven structuring of the placed circuit. The second conveyor operating at the second speed allows a second spaced configuration of the workpiece carriers.
