Customization methodology for integrated circuit design customization using a software tool that integrates multiple integrated circuit development operations. The selective bypass circuit includes a capacitor, two ferrite beads, and a solid-state relay. The assembly includes an engagement device for preventing sliding movement of the bed knife with respect to the bed bar while allowing the bed knife to move away from the bed bar and backing plate when a separating force is exerted on the bed knife in a direction away from the bed bar that is greater than an attractive force exerted on the bed knife by the bed bar.
