Function variable type cell and semiconductor integrated circuit and its design system

摘要

PPROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit capable of corresponding to specification change and bug correction after the semiconductor integrated circuit is manufactured. PSOLUTION: Standard cells 101 used in a cell base IC and function variable cells 102 are mounted on the semiconductor integrated circuit. A function variable cell 102 is provided with a means for controlling at least one among function change, function stopping and function activation with a control signal inside the semiconductor integrated circuit or a control signal given to the semiconductor integrated circuit from the outside.
