lc complementary oscillator start up

Hi guys,

What kinds of simulations (in cadence) do I have to run if I need to make sure my complementary CMOS LC oscillator will definitely stary to oscillate?

Simulate the overall 1/gm and make sure it is 2~3 times bigger than the LC impedance maybe a way, but what I heard is that is not accurate...

Thanks,

gould
