7. Use a FSM to implement a counter with RESET function. The counter should meet the following requirements:
(1) The counter counts 0, 2, 1, 3, 0;
(2) The RESET is asynchronous, not synchronized with the CLOCK signal. If RESET signal is low, the counter resets to 0.
Please provide the state bubble diagram, state table, K-Maps, schematic for the counter.

Provided the d flip flopp IC 74LS74 as active low reset which is asynchronous in nature which meets our requirement of rest ( active low pin ) in the design
When Reset is low the d flip flop output will be set to "0" making both flip flops output Q1 = 0 , Q0 = "0" ;
Which makes current state S0 and output C1 , C0 = 00
Thus our requirement is achieved with the help of Reset present at the flip flop inputs in the FSM implementation

Use a behavioral Verilog model to design a 3-bit fault tolerant up-down counter. For each flip-flop (FF) include asynchronous reset and preset signals. Refer to Example 4.3 on page 160 for an example of a single FF with both reset and preset signals as well as with an enable signal. For this project, you don't need to use FFs with enables. You don't also need not-q (nq) in this assignment. Use active-high signals for reset and present signals. The example...
