Patent attributes
A semiconductor integrated circuit comprises: a first area, formed on a semiconductor chip, which operates at a first predetermined voltage and a first predetermined frequency; a second area, formed on the semiconductor chip, which operates at a second voltage and a second frequency lower than the first voltage and the first frequency, respectively, and also operates after a shift to the first voltage and the first frequency; and a third area, formed on the semiconductor chip, which operates at the first voltage and a frequency which operates the second area and transmits and receives signals sent between the first area and the second area; the third area possessing a delay analysis endpoint that can analyze each of a first delay occurring between the first area and the third area and a second delay occurring between the second area and the third area.
