problem through simulation of LDI(lossless discrete integrator) resonator using spectre

i have simulated LDI resonator using spectre , in the right case and other simulator like lt-spice my output oscilate with my resonance frequency in the form of a pulse shape waveform ( like clock generator ) . but in the cadence my waveform is like following picture ( attachment file here ) i dont know what to do ?? because my circuit and everythings are correct but the waveform not !and my second problem is that , my waveform eventually converge to the zero ! why ????? if i increase the gain of my micro model opamp i 've just increase the time of convergance , but again eventually it will be converge to the zero (as follow pictures )

if any body can help me, i will be grateful

best regards
