EQUIPMENT AND METHOD FOR DISTRIBUTING CLOCK TO CIRCUIT CONSTITUTING ELEMENT OF INTEGRATED CIRCUIT

摘要

PURPOSE: To supply synchronous clock signals to the entire components of an integrated circuit with minimum signal skewness and distortion by uniformly arranging a plurality of global clock driver means for generating the synchronous clock signals along the periphery of the integrated circuit. CONSTITUTION: Global clock drivers 30 are arranged along the left and right ends of a microprocessor 200 and the respective global area drivers 30 send clock signals into the center part of the microprocessor 200 by a feed line 31. A common driver 301 supplies the clock signals through a common supply line 303 and common networks 340-344 to intermediate clock drivers 310-314. The intermediate drivers 310-314 are connected through intermediate networks 361-365 to the global area drivers 30. The respective lines of the common networks 340-344 are provided with similar RC values and thus, matching is performed relating to the resistance and capacitance values so as to be provided with the matched skewness.
