Binary/Gray Counter Design

The basic steps in the design process are as follows. Your design must be complete and fully documented as part of the PREPARATION.

1.

Complete the state diagram (HLAB3).

2.

Draw tables showing all state transitions, inputs and outputs.

3.

Draw a circuit diagram which implements the counter using D flip flops as memory elements:

(a)

List all input, output and state codings, all relevant next-state and output tables in terms of these codings.

(b)

Give all K-maps for the state transition functions and output functions.

4.

Create a schematic project for the binary/gray counter:

(a)

Enter your circuit as a schematic diagram. Add to your project.

(b)

Carry out simulation testing of your design.

(c)

Revision of your design as needed: does it meet the specs?

5.

Include all calculations, drawings, schematic printouts and simulation waveforms in your notebooks.
