Question

Draw the Moore machine state diagram with minimal states for the digital alarm clock system(both of time set and alarm set)

Design a digital alarm clock that has the following ports:
Inputs:
CLK_1_SEC, RST, LOAD_TIME, SET_HOURS, SET_MINS, SET_SECS, SET_AM_PM,
LOAD_ALM, ALARM_HOURS, ALARMS_MINS, ALARMS_AM_PM, ALARM_ENABLE,
ALARM_DURATION
Outputs:
HOURS, MINS, SECS, AM_PM, FLASHING, ALARM
The required characteristics of the digital alarm clock are:
• timing it to be controlled from a 1 second input clock, CLK_1_SEC
• to operate on 12-hour basis with separate AM/PM control
• the value of time to be set when LOAD_TIME is high
• the alarm time to be set when LOAD_ALM is high
the ALARM output should go high when the current value of time is equal to the alarm
time. The alarm should stay on until the ALARM_ENABLE signal goes low, which equates
to turning the alarm off or after ALARM_DURATION minutes has elapsed when left on
or RST/LOAD_ALM signal is set high. Note ALARM_DURATION can be lower than or
equal to 10 minutes.
• If power is lost and then powered up again, it should stay the time 00:00:00 and the
"Flashing" signal should be activated high. This causes the display to flash and so indicate
that the alarm clock's time needs to be set. The flashing signal should stay high and the
clock's time should increase from zero until a new time is set.
Draw the Moore machine state diagram with minimal states for the digital alarm
clock system (both of time set and alarm set).
