CLOCK SIMULATOR AND CLOCK SIMULATION METHOD

A clock simulator and a clock simulation method are provided to calculate the change in stability due to the change of an algorithm when designing a clock system using a plurality of clocks and in consideration of the influence on the movement of clocks by changes of various design variables. A clock simulation method comprises the following steps of: receiving inputs for the operation of clocks, control and movement from a user(S10); making the operation-related input into an internal variable based on the inputted data and the movement-related input into a polynomial coefficient and h-parameter, and calculating a control frequency for the control-related input(S20); calculating a deterministic trend from the polynomial coefficient and control command as matching the time interval based on the initialized data, and generating/adding up a plurality of noise components from the h-parameter(S30); and arranging/outputting the clock output based on the reference time(S40).
