Abstract: A minimum IC operating voltage searching method includes acquiring a corner type of an IC, acquiring ring oscillator data of the IC, generating a first prediction voltage according to the corner type and the ring oscillator data by using a training model, generating a second prediction voltage according to the ring oscillator data by using a non-linear regression approach under an N-ordered polynomial, and generating a predicted minimum IC operating voltage according to the first prediction voltage and the second prediction voltage. N is a positive integer.
