Abstract: A wiring design system when applied to wiring boards having various wiring restrictions, has a rough wiring plan at the floor plan stage so as to complete a wiring design satisfying the wiring restrictions in a short period of time while evaluating the congestion degree of the wiring. Logical connection information for wiring parts and signal group information for handling the connection information is input as a signal group. The signal group is handled as a wiring unit for a wiring path search and the signal group is divided into smaller groups. An optimum path is then determined in such a way that the divided smaller groups run adjacent to one another whenever appropriate.

Abstract: By deciding a draw wiring route from a part to eliminate an intersection of wire connections generated by the part direction and the terminal arrangement order, it is possible to reduce the wiring layer used and increase the mounting density. Draw wiring processing from terminals of parts is performed prior to the entire wiring processing. In order to optimally perform the draw wiring processing, the parts connected to an object to be wired are moved onto a virtual wiring board and wiring processing is performed there. When moving a part from the real wiring board, an area around the part is cut out from the real wiring board and moved onto the virtual wiring board. On the virtual wiring board, the part direction is rotated and parallel-displaced to arrange it in the optimal state for the wiring to decide the draw wiring direction and perform wiring between the respective terminals.

Abstract: Each flip-flop-to-flip-flop path delay and a target machine cycle obtained in the stages of physical design and packaging design are used as input, and with respect to a path in which the path delay is not less than the target machine cycle, a closed loop including the path is extracted, and the timing of a clock signal of each flip-flop is adjusted so as to permit data transmission along the closed loop in a required cycle-number. At this time, a path along which data transmission is impossible in the target machine cycle or a closed loop including the path is listed in order to be modified. As methods of supplying a clock signal to each flip-flop, a plurality of methods different in the adjustable range of clock timing are combined and used.

Abstract: A desired value of reactive power flow between a to-be-controlled power system and an adjoining power system is determined according to measured values of the reactive power flow and an effective power flow and desired voltage values of the to-be-controlled power system and of the adjoining power system. Thereafter, a required value of a reactive power of the to-be-controlled power system is calculated according to the desired value of the reactive power flow, the measured values of the reactive power flow and the effective power flow, and the desired voltage value and a measured voltage value in the to-be-controlled power system. Thereafter, a control apparatus having an electric capacity near to the required value of the reactive power is selected from control apparatus arranged in the to-be-controlled power system to make the selected control apparatus adjust a voltage of the to-be-controlled power system.
