We have used the circuits from previous labs as components in this design. You need to extend labs so that it uses six 7-segment displays rather than just one. You will need to use six instances of each of the components. The purpose of your circuit is to display any word on the six displays that is composed of the characters in Table 1, and be able to rotate this word in a circular fashion across the displays when the switches GPIOs are toggled. As an example, if the displayed word is ABCDEF, then your circuit should produce the output patterns illustrated in Table B Example is provided as the following: Suppose we have input of SWS: SW SW SWS SW.4SW SW2SW. SW. SW, SWSWSW. SWS SW.SW, SW, SW, SW 000001 010 010 011 100 D Then the rotating character patter is decided by multiplexer select lines of GPIO, GPIO, GPIO, the result will show: GPIO, GPIO, GPIO HEX5 HEX4 HEX3 HEX2 HEX1 HEXO 0 0 0 A(SW17-SW 16) B(SW14-12) C(SW11-9) DISW8-6) E(SW5-3) F(SW2-0) 0 0 1 B 0 1 0 0 1 1 100 101 Inputs: GPIO, GPIO, GPIO provide the multiplexer select lines SW17-0 provide six 3-bit codes used to select characters Outputs: LEDR shows the states of the switches HEXS – HEXO displays the characters (HEX7-HEX6 are set to “blank”) PART 1: Perform the following steps. 1. Design your circuit in detail to meet the requirement 2. Create a new Quartus II project for your circuit 3. Copy the design entries for the three-bit wide 6-to-1 multiplexer and the 7-segment decoder from previous to your current design folder. 4. Create bdf symbols for the three-bit wide 6-to-1 multiplexer and the 7-segment decoder, respectively. Include your entity in the Quartus Il project. You can insert the symbols you created from step (3). Connect the switches from GPIOs to the select inputs of each of the six instances of the three-bit wide 6-to-1 multiplexers. Also connect SW17-9 to each instance of the multiplexers as required to produce the patterns of characters shown in Table 2. Connect the outputs of the six multiplexers to the 7-segment displays HEX, HEX, HEX, HEX, HEX, and HEX 6. Include the required pin assignments for the DE2 board for all switches, GPIOS, LEDs, and 7-segment displays. 7. Compile the project.
