Im simulating a pierce crystal oscillator on synopsys software. The design that i've made is to achieve 10MHz frequency. The problem is the circuit that ive made doesnt oscillate. Initial condition also been included before the inverter. Is there any error that I've made in this circuit? Thank you


RF = 1M Ohm
R1 = 1k Ohm
C0 = 6p F
Cstray = 5p F
C1 = C2 = 22p F
Pmos W/L = 6u/1u
Nmos W/L = 3u/1u
