How it works

Its a simple FSM with 3 states (Idle, Waiting and Alarm) and counters regarding clk_cycles, seconds and minutes...

How to test

Set the clock to 10kHz, set the wait time you want (in minutes) by setting io_in[7:3], set the start switch to 1, the timer should be running, the dot of the 7segment display should toggle each second. If the time is expired, an A for alarm should be displayed. You can stop the alarm by setting the start switch to 0 again.
