A three-state gate has a control input that can be place the gate into a high impedance state. The high-impedance state is symbolized by z in Verilog. There are four types of three-state gates. The buffif1, buffif0, nitif1, notif0 has different behavior that was indicated by a bubble in the input and output of the three-state gate. The buffif1 behaves like a normal buffer if control=1. The output goes to high impedance state z when control=0. The buffif0 behaves the same except that the high impedance occurs when the control is equal to 1. The notif0 and the notif1 gates operates in similar manner, except the output is the complement of the input when the gate is not in the high impedance state
