Abstract

Disclosed is an IC voltage determining method including: executing a static timing analysis according to a circuit design to obtain data of a critical path and then generating a netlist; executing a circuit parameter simulation and Monte Carlo simulation with the netlist according to a regular voltage and prescribed parameters to obtain a circuit parameter reference value and a variance of circuit parameter values; executing an adaptive voltage scaling analysis according to a voltage range to obtain a voltage-versus-parameter relation indicative of the number of times that each of circuit parameter deviations that are respectively associated with predetermined voltages within the predetermined voltage range is of the variance; and testing an IC according to the regular voltage to obtain a circuit parameter test value and determining the IC voltage according to the voltage-versus-parameter relation and a difference between the circuit parameter test value and the circuit parameter reference value.
