Transient Noise Analysis$ m4 C; U& F3 x: H
HSPICE’s transient noise analysis enables users to predict the effects of device noise (channel, thermal, flicker, and shot noise) on time domain waveforms. HSPICE offers two powerful approaches for simulating transient noise. ) C2 x% z, ^6 [! a4 D/ a( \; _/ I9 c- q& ?+ J
Monte Carlo approach: Monte Carlo samples generate an ensemble of noise stimulated waveforms for statistical evaluation. HSPICE supports noise bandwidth and scaling controls and enables the user to plot histograms of the simulation results.1 [$ }1 J' k$ d/ N/ M

SDE noise measurements reveal waveform uncertainty and results can be used to predict circuit jitter due to device noise., ~8 E! D/ g" i; v& y% D

不過,我本人還沒有用過,以后打算用。不過總之應該是可以的,你可再搜索一下資料。作者: fet 時間: 2010-1-12 09:00 AM
