The invention relates to a coil component used as a major component of a common mode choke coil or transformer and a method of manufacturing the same, and the invention is aimed at providing a compact and low-profile coil component having a high common mode filtering property and a method of manufacturing the same. The control cartridge has a control shank which is pivotably mounted in the control cartridge. The first nonvolatile memory includes a first portion of memory that is protected and is readable when a shield bit indicates an unshielded mode of operation, but is unreadable when the shield bit indicates a shielded mode of operation and a second portion of memory that is unprotected and that is readable regardless of the value of the shield bit. This conserves string and is safer. Then, in response to determining that the updated slack values at the endpoints of the zone do not degrade one or more circuit timing metrics, the system applies the leakage-power-reducing transformation to the logic gate.
