该博客介绍了如何设计一个电路来控制手机的铃声和振动电机。当有来电时，电路根据输入的震动模式决定开启铃声或振动电机，确保二者不同时启动。如果手机处于震动模式，将启动振动电机；否则，将启动铃声。

Suppose you are designing a circuit to control a cellphone's ringer and vibration motor. Whenever the phone needs to ring from an incoming call (input ring), your circuit must either turn on the ringer (output ringer = 1) or the motor (output motor = 1), but not both. If the phone is in vibrate mode (input vibrate_mode = 1), turn on the motor. Otherwise, turn on the ringer.

module top_module (
    input ring,
    input vibrate_mode,
    output ringer,       // Make sound
    output motor         // Vibrate
);
    //来电且非震动
    assign ringer = ring && ~vibrate_mode;
    assign motor = ring && vibrate_mode;

endmodule
