Semiconductor integrated circuit for reducing crosstalk and method for designing the same

摘要

A semiconductor integrated circuit includes a logic circuit, a first switching cell connecting a first power supply line with a first virtual power line so as to drive the logic circuit, and a second switching cell connecting a second power supply line with a second virtual power line so as to drive the logic circuit. A time constant defined by the product of resistance and capacitance, which are measured between the first virtual power line and the first power supply line, is held to a constant value.
