Conventional Alarm Clock

Brief

Your journey begins by designing a conventional alarm clock using Digital, and learning the basics of digital timekeeping.

Goals

Learn how to use Digital
Create a clock capable of:
- Displaying the current time
- Setting the current time
- Setting the alarm time
- Sounding an alarm at a user-defined time

Failure to follow this structure can result in grading of the lab to be delayed or incorrect.

Your main Digital circuit should be named as ConventionalAlarmClock. The following ports should be opened for the ConventionalAlarmClock:

Port Direction	Port Name	Active	Port Width (bits)	Description
INPUT	`CLK`	Rising	1	Clock input used for the alarm clock
INPUT	`CLR`	High	1	Resets the alarm clock
INPUT	`SETUP_TIME`	High	1	Allows the user to set the time using `MIN_ADV` and `HR_ADV`
INPUT	`SETUP_ALARM`	High	1	Allows the user to set the alarm using `MIN_ADV` and `HR_ADV`
INPUT	`MIN_ADV`	High	1	Increments the minute signal whenever either `SETUP` signals are active
INPUT	`HR_ADV`	High	1	Increments the hour signal whenever either `SETUP` signals are active
INPUT	`ALARM_EN`	Low	1	Enables the buzzer when the alarm time is reached
OUTPUT	`SECONDS`	-	6	The current seconds the alarm clock has stored
OUTPUT	`MINUTES`	-	6	The current minutes the alarm clock has stored
OUTPUT	`HOURS`	-	5	The current hours the alarm clock has stored
OUTPUT	`ALARM_MINUTES`	-	6	The minute that the alarm clock is set to `BUZZ` at
OUTPUT	`ALARM_HOURS`	-	5	The hour that the alarm clock is set to `BUZZ` at
OUTPUT	`BUZZ`	High	1	Signal to buzz an external alarm when the alarm time is reached
OUTPUT	`SEG_SECONDS`	-	14	Seven segment signal for the seconds the alarm clock has displayed
OUTPUT	`SEG_MINUTES`	-	14	Seven segment signal for the minutes the alarm clock has displayed
OUTPUT	`SEG_HOURS`	-	14	Seven segment signal for the hours the alarm clock has displayed
