Digital State Machine Design
Budget: $30 – $250 USD
I need to make a statemachine in Multisim, please let me know if you can do it, below are the requirements I have been assigned. If you can do this please let me know and I will give you the words I need to display. I need to use D flipflops, seven segment display, logic gates if needed, spdt switch, dcd_hex display and a minimum of 6 states.
Design and simulate a State Machine that will spell out a specific word when En=1 and a different word (using the same list of letters) when En=0. For example, if you had states which displayed the letters AHINORT you could spell T-H-O-R-N if En=1 and spell T-R-A-I-N if En=0. Use the provided WORD LIST to find pairs of words that use some (if not all) of the same letters.
Use a minimum of 6 states, no duplicate letters allowed. (Ex: “onion” has “o” twice) - All letters listed must be used at least once.
Your 2 words must have a combined length of at least 10 letters (minimum length of 4 letters per word) and cannot have more than 2 consecutive letters that match (i.e. “team” & “material” is okay, however “sting” and “thing” is no good). Words must be approved before you begin.
Use a Common Cathode (CK, 1 = “on”) OR Common Anode (CA, 1 = “off”)seven segment display to show your words.
Use ANY additional logic gates you deem necessary to complete your design from the 74LS Part family ONLY.
An SPDT switch must be used for the ENABLE (assign Key = E) to choose the displayed word.
A DCD_HEX display or probes must show the current state, labeled as such, and be located next to the 7-segment display.
Deliverables (use included template for your table and maps)
State Diagram/State Graph, drawn or created neatly defining all state variables, letters & transition arcs. Make S0 the initial state. States MUST BE set up in alphabetical order, based on the letters being displayed.
State Transition Table (use “don’t cares” where appropriate).
K-Maps, 10 of them, completed neatly with matching simplified expressions for each Flip-Flop Input (Da, Db & Dc) and the 7 Encoded Outputs to the Seven Segment Display (a - g).
A working simulation which is fully labeled with title block (include your names, class periods or section #) and your Words shown with EN =0 or EN = 1..
