Abstract
Disclosed are a semiconductor device of which a block having a plurality of portions that operate based on a plurality of clocks can be designed and inspected easily, and a method of designing the semiconductor device. First and second clocks whose frequencies are mutually different are used to generate an enabling signal that is validated only during a short period including a transition edge of the second clock. The enabling signal and first clock are supplied to the second portion. The second portion synthesizes the enabling signal and first clock to substantially generate the second clock. Thus, the second portion is regarded as a portion that operates synchronously with the first clock.
