Ringer.v

// 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.
// Try to use only assign statements, to see whether you can translate a problem description into a collection of logic gates.

    input ring,
    input vibrate_mode,
    output ringer,       
    output motor
