Provided is a method of incremental SSTA (statistical static timing analysis) of a digital circuit, the method including a first step in which, when a gate is replaced in the digital circuit, delay propagation is performed from a node of a replaced gate to a virtual sink node based on SSTA; a second step in which, if a changed value of a gate timing yield at each gate which propagates delay toward the virtual sink node is smaller than a predetermined threshold value, delay propagation with respect to a fanout gate of the corresponding gate is stopped; and a third step in which, when a delay with respect to the node of the replaced gate is propagated to the virtual sink node, a new timing yield is calculated at the virtual sink node.

The present invention relates to an apparatus and method for controlling power to a Universal Serial Bus (USB) device. The present invention provides an apparatus for controlling power to a USB device, the USB device being used to connect a Personal Computer (PC) with a peripheral device, the power control apparatus including a plug-in port for connecting the peripheral device with the PC, a state detector for detecting whether the peripheral device is in a preparation completion state, a power supply unit for supplying power to the USB device, and a power control unit for controlling the power supply unit so that power is supplied to the USB device if it is determined that the peripheral device is in a plugged-in state, and if it is determined that the peripheral device is in a preparation completion state by the state detector. Accordingly, the present invention performs the supply of power only when the peripheral device is plugged into the USB device and its internal application program is in a preparation completion state, so that it can prevent power from being unnecessarily consumed.

Provided is an electromagnetic bandgap (EBG) structure, and particularly, an overlay EBG structure in which a plurality of vias and a plurality of plates are formed at intervals on a central signal line in such a manner that the vias and plates extend vertically from a substrate in order to reduce leakage loss of an electromagnetic wave through the substrate. Therefore, it is possible to prevent an electromagnetic wave passing through a transmission line from being lost through the substrate, to obtain desired frequency characteristics by adjusting the dimensions of the vias and plates, and to manufacture the overlay EBG structure using an existing CMOS process without having to perform any additional process.
