Abstract: PURPOSE:To improve discharge ignition efficiency by previously charging a spark plug with voltage of such a value as the spark plug is impossible to discharge in the first half of one cycle, while making the spark plug to discharge by voltage of polarity, different from the above mentioned, in the latter half of the cycle. CONSTITUTION:A power transistor Tr8 is turned off by cutting off its base voltage for a predetermined time in the case of inputting a trigger signal from a trigger circuit 4 to a timing circuit 3, so that positive high voltage, induced in a secondary coil 5, is applied to a spark plug by giving counter electromotive force to a coil 6a. Here the voltage, induced in the secondary coil 5, is set to such value as the spark plug 1 does not discharge, and center electrode of the spark plug 1 is charged with positive electricity while the peripheral electrode of the spark plug 1 is charged with negative electricity. After a predetermined time, the transistor Tr8 is turned on and the other transistor Tr9 is turned off, so that counter electromotive force is given to a coil 6b, and discharge is performed by inducing negative high voltage in the secondary coil 5 to be applied to the spark plug 1.

Title: Method of designing semiconductor integrated circuit
Inventor: SATO KAZUHIRO
IPC: H01L21/82
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To suppress speed performance deterioration caused by a wiring capacity, etc., by adopting a relay buffer insertion method, and in addition, to realize a low-clock skew that does not rely upon voltage or temperature characteristics. SOLUTION: In a block 1 adjoining the route from a clock-supplying source to a clock-supplying destination, the disturbance to a signal line passing through a wiring inhibiting region 5 can be avoided by generating an arrangement inhibiting region 5 and the wiring inhibiting region 5 in the block 1 along the clock-wiring path-side edge. In addition, since relay buffers 4 are arranged in the regions 7 and 5, delay adjustment can be performed without correcting the arranged positions of cells. Moreover, a circuit which does not rely upon voltage or temperature characteristics is generated, by making a wiring delay and a cell delay equal to each other, by making the wiring of clock signals to each destination with the same length and the same capacity.
