Hi, I found it strange when I simulate the crystal oscillator with tran analysis in spectre. When I set the initial current of 1uA in the parameter of CDF of the inductor in the crystal model, I observed that the current of the inductor(sin wave) starts from 0 and begin to oscillate with 1mA amplitude, when I set it of 1mA, it starts from 0 and begin to oscillate with 1A amplitude. Then the envelope begin to decay to a stable value about 900uA. So, I am confused about relation ship between the initial current in the component parameter and the value at time 0, also the initial swing of the inductor current. And how can I set the initial current in the inductor in order to make the crystal oscillator reach the stable state quickly? Thanks.
