Hello, I am using a nanowire transistor model to design LC tank VCO in Cadence (Spectre). I am targeting for very high frequency (more than 100GHz). Some how the simulation is taking very long time and the waveform gets stable for 4ns (approx.) and amplitude increases. I am not sure why it's happening. I am kind of suspecting the model of transistor. I was wondering if there is any way to characterize this transistor for its proper characters. I already performed DC analysis. It has really high ft and fmax. Thank you in advance.
