ABSTRACT:
An information processing apparatus is constructed by a system PLL, a first unit, a second unit, and a system board on which they are mounted. A delay setting circuit in which a variation and delay elements (a gate delay and a line delay) which are equivalent to those of a clock tree circuit for a gate have been set at the designing stage is provided on a signal line of a system clock in the first unit to the second unit. A delay setting circuit in which a variation and delay elements which are equivalent to those of the clock tree circuit for the gate have been set at the designing stage is provided on a signal line of a clock gate signal to the second unit.
