摘要: In this paper, a low-cost method to verify functional specifications of analog VLSI circuits is proposed. The based on the analysis Lissajous signatures combined with regression techniques. order obtain signatures, observation space partitioned into zones using hyperplanes, and set integer values used as digital signature circuit generated by curve zone crossings. A predictor function obtained nonlinear techniques predicts specification parameters under consideration. viability methodology analyzed applied center frequency f 0 bandpass biquad filter. Experimental measurements show an accurate prediction designed
