发明名称 Spread spectrum verification circuit
摘要 A method for verifying a spread spectrum function and a spread spectrum verification circuit are provided. Comparing an output frequency of the spread spectrum function with a reference frequency for the spread spectrum function tests an upper bound of the spread spectrum function. If the output frequency increases above the reference frequency, the upper bound of the spread spectrum function is verified. Comparing the reference frequency for the spread spectrum function with the output frequency of the spread spectrum function tests a lower bound of the spread spectrum function. If the output frequency decreases below the reference frequency, the lower bound of the spread spectrum function is verified.
