<p>PURPOSE:To supply a clock signal which has a small clock skew to plural function blocks in a semiconductor chip. CONSTITUTION:A predriver 52 which is arranged at a specific position and drives the clock signal and branching electric conductors 53, 54, and 55 of plural stages which transmit the output of the predriver are provided in the semiconductor chip 50. Further, the circuit is provided with plural main drivers 56, 57, 58, and 59 which are arranged at an equal distance from the predriver 52 through the branching electric conductors 53, 54, and 55 and drive the output of the predriver 52 and a main trunk line 60 which is arranged at the center part of the semiconductor chip 50 and also connected to the output sides of the respective main drivers 56, 57, 58, and 59 to send the outputs of the main drivers 56, 57, 58 and 59.</p> |
