[Solved] SOLVED:Computer Assignment 2

Assignment Overview

In this assignment you will use Vivado 15.2 Webpack to write and simulate a hex to seven segment display convert. Youll also need to turn in a single PDF to Moodle (instructions below).Background A seven segment display is a way to display a decimal or hex digit. There are various ways to label the segments of the display or encoding the digit, but below is what were using for this computer assignment.Figure 1: Seven Segment Display Layout source http://www.lucky-light.com/LED%20Displays/Four%20Digit%20Display/KW4-281.pdf (seven segment display on the Basys3)Figure 2: Hex Encoding source http://www.faculty.etsu.edu/tarnoff/labs2150/dig_apps/sevenseg.htmin(3) in(2) in(1) in(0) A B C D E F G0 0 0 0 1 1 1 1 1 1 0 0 0 0 1 0 1 1 0 0 0 0 0 0 1 0 1 1 0 1 1 0 1 0 0 1 1 1 1 1 1 0 0 1 0 1 0 0 0 1 1 0 0 1 1 0 1 0 1 1 0 1 1 0 1 1 0 1 1 0 1 0 1 1 1 1 1 0 1 1 1 1 1 1 0 0 0 0 1 0 0 0 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 0 1 1 1 0 1 0 1 1 1 0 1 1 1 1 0 1 1 0 0 1 1 1 1 1 1 1 0 0 1 0 0 1 1 1 0 1 1 0 1 0 1 1 1 1 0 11 1 1 0 1 0 0 1 1 1 1 1 1 1 1 1 0 0 0 1 1 1 Table 1: Truth Table of the EncoderGetting started 1. Create a directory to store all of the assignments files. 2. Open Vivado 2015.2 and create a new project called computer_assignment_2. 3. It will be an RTL project 4. No sources to input. Although if the target and simulation languages arent set to vhdl, change them to vhdl. 5. No existing IP. 6. No constraints file. 7. The Basis3 uses an XC7A35T-1CPG236C FPGA Artix 35T Speed grade 1 CPG236 packaging C temp gradeTask This task is to implement a encoder which input is a 1 4-bit hex signal and the output is 7 1-bit signals for each display segment (A-G). 1. Create the encoder.vhd file: a. Under Flow Navigator click Add sources. b. Select Create or add design sources. c. Create task1.vhd and then click Finish. d. Create an input named hex_in which is 4 bits wide. e. Create 7 outputs named A throught G. 2. Once you have your vhdl source file, edit it to implement the encoder. A when/else or if/else statement might be helpful A internal signal of the outputs grouped together as a bus might help clean up the code 3. Make sure its syntax error free and can be be synthesized. 4. Add the encoder_tb.vhd file: a. Under Flow Navigator click Add sources. b. Select Create or add simulation sources. c. Add encoder_tb.vhd. d. Make sure simulation set is sim_1. e. Click Finish. 5. Select the right simulation set: a. Under Flow Navigator click Simulation Settings. b. Under Simulation set input sim_1. c. Under Simulation top module name input encoder1_tb. d. Click Ok. 6. Run the simulation by and check your results. The expected output is on the last page of the assignment. 7. Vivado doesnt include a way to print test bench results so you will have to take a clear screenshot of at least one iteration of the circuit.Turn in The write up is very simple, just include things like: the basic design process, anything you had trouble with, an explanation of anything doesnt work, etc. It isnt meant to be extension, but a brief overview.Make sure everything is in a single PDF on Moodle. You can join PDFs with Adobe Acrobat if you have multiple PDFs. Name the assignment CAD2-xxxxxx-yyyyyy, where xxxxxx is the last name of one lab partner and yyyyyy is the last name of the other lab partner. Turn in only one pdf under one of the lab partners Moodle account.Make sure everything is in a single PDF on moodle. You can join PDFs with Adobe Acrobat if you have multiple PDFs.Grading Write up /4 Points Printout of encoder.vhd /8 Points Printout of encoder_tb simulation results /8 Points/Total of 20 Points
