A Source Code

Source code for the project may be obtained on GitHub: https://github.com/

gajjanag/6111_Project. For completeness, we include all source code here as

well. For ease of browsing through the code, we have divided the modules into

roughly three categories:

• Staﬀ Modules: modules that are essentially the same as staﬀ provided

modules, with minor modiﬁcations for our speciﬁc needs.

• Labkit: top level labkit module with general instantiations, including clock

generators, and ucf ﬁle

• Our Modules: modules created by us for our project

A.1 Staﬀ Modules

A.1.1 debounce.v

1 // Switch Debounce Module

2 // use your system clock for the clock input

3 // to produce a synchronous, debounced output

4 module debounce #(parameter DELAY=270000) // .01 sec with a 27Mhz clock

5 (input reset, clock, noisy,

6 output reg clean);

8 reg [18:0] count;

9 reg new;

11 always @(posedge clock)

12 if (reset)

13 begin

14 count <= 0;

15 new <= noisy;

16 clean <= noisy;

17 end

18 else if (noisy != new)

19 begin

20 new <= noisy;

21 count <= 0;

22 end

23 else if (count == DELAY)

24 clean <= new;

25 else

26 count <= count+1;

28 endmodule
