DELAY CIRCUIT, SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE WITH THE DELAY CIRCUIT, AND DESIGN/DEVELOPMENT METHOD FOR THE SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a delay circuit that can reduce a design period required for a timing adjustment while suppressing increase in the difficulty of the design itself.;SOLUTION: The delay circuit is provided with a delay section 2 that controls the delay time and includes delay elements 4 connected in series, a data input terminal 5 receiving data S, switches 6-1 to 6-6 connected in parallel between each input of the delay elements 4 and the data input terminal 5 and with a control section 3 that controls the delay time of the delay section 2 by controlling the switches 6-1 to 6-6 and includes flip-flop circuits F/F1-F/F5 that receive external serial control data DATA and are connected in series.;COPYRIGHT: (C)2002,JPO
