Race Conditions

• Going from the state 011 to 110 changes two bits, one of which can change first (but this is random)
  • You might temporarily be in the state of 111 or 010 which is read by the combination circuit (which doesn’t rely on clock timings!)
  • This is a race condition and are often unsafe
  • In the example outputting high when111 occurs, going from 011 to 110 may cause problems, so we have to accommodate that
    • 010 is not a problem cuz it’s not the 111 we seek
