摘要
In automatic placing and routing, a standard cell 101 is composed of a P-channel transistor region 102 and an N-channel transistor region 103. The P-channel transistor region 102 has a P-channel functional transistor forming region 104, and the N-channel transistor region 103 has an N-channel functional transistor forming region 105. In a space region of the N-channel transistor region 103 other than the N-channel functional transistor forming region 105, a power source capacitor forming region 106 is formed at a portion of the P-channel transistor region 102 opposing the P-channel functional transistor forming region 104. In this region, a power source capacitor is formed to suppress the IR-Drop of a power source wiring line.
