The Cyclone II EP2C20F484C7 FPGA on the DE1 logic kit is connected to four seven segment displays, (Hex_0, Hex_1, Hex_2, and Hex_3), ten slide switches (Switch_0 through Switch_9), four push buttons (Key_0 through Key_3), ten red LEDs (Red_LED_0 through Red_LED_9), and eight green LEDs (Green_LED_0 through Green_LED_7).

The slide switches produce logic “1” when pushed away from the edge of the board, and the push buttons produce logic “0” when pressed. The segments of the seven segment displays light up when connected to logic “0,” and the LEDs light up when connected to logic “1”. The following table shows which FPGA pin numbers are connected to these devices.

The segments of a seven-segment display are normally named A–G, starting at the top, going clockwise, and ending with the center segment. The array names in the table refer to the segments using subscript values 0–6 in the same order.

To make the process of pin assignment easier, the following table is in alphabetical order, which should match the order of the pins listed by the Quartus Pin Assignment Editor, provided you name your pins and pin groups alphabetically: Clock…, Green…, Hex_0…, Hex_1…, Hex_2…, Hex_3…, Key…, Red…, and Switch… in that order.

32 For changes to take effect recompile project
Once recompiled, download it to the boardNote: The circuit will be larger than beforeMemory is used to store captured data

33 Setup Event Trigger Click here to begin capture
UPDATE screenshot (DE-SoC vs SoCKit)! Sample depth! When the event occurs, it will store the data for x cycles (ex 128 shown) and display the data. Some cycles worth of data before the event as well.

34 Trigger the event and Analyze the results
Use same circuit as previous example (if use previous, LEDS might not shift. Would have to get rid from analyzer).

Simple circuits connecting lights, multiplexers. Later exercises become more advanced and use the simpler circuits from previous exercises, and build more advanced circuits. Fits very well with the way that you would teach a course like this are advanced, not for beginner courses.383838

39 Lab Exercises and Solutions
Exercises and complete solutions on U.P. web sitePassword protected (Professors/Lecturers)Includes all Quartus II projectsIncludes all figures and source text (allows Instructors to add their own material)RETAKE pic to include exercise 11,12. Also remove part5.Verilog from document_files. We ALSO provide the latex files for the lab writeups so that you can modify them for your course. Mention that we provide verilog AND VHDL solutions and writeups.393939

40 Organization of Lab Exercises
Simple HDL assignments that directly correspond to Boolean equationsNo magic!Block-based design in which each block of code corresponds to a well-defined subcircuitHDL code is not a “program”!!Smaller circuits are built first, and then used to construct larger onesGood design practiceWe though carefully about how to present the exercises to ensure they learn properly. Ex. In first few examples, students cant use advanced verilog features. Can only use boolean eequations. Want students to know they are designing circuits. Type of verilog code we show clearly corresponds to a circuit; easy to see that each part of the code corresponds to circuit. Smaller -> larger, good design practice used in industry.404040

41 Lab 1: Switches and Lights

Lab 1: this is the beginning point. Part 1 assumes students don’t know anything. Open the solution .v. Move on to part 2 the simplest circuit that you can use to build a circuit.414141

44 … Lab 1 Make 5 copies of this Suggested solution Part 5 Part 5
Putting together the circuits from the previous parts, you ave the ability to display character patterns. Using only simple 2-1 muxes and a 7-seg decoder, we can make an interesting circuit that can rotate a word across the display. Emphasize hierarchichal fashion small -> largerSuggestedsolution444444

48 To Students: Write “Obvious” HDL Code
Comparatorassign T = A + B;(T)if (T > 9)beginZ = 6; C = 1;endelseZ = 0; C = 0;assign S = T + Z;AdderMultiplexer that selectsconstantsEven when we allow students to use more advanced features of verilog, still make sure each line clearly corresponds to a piece of the circuit. A nice feature of Quartus is to use the RTL viewer to display that the circuit described is actually what you are expecting.Adder484848
