www.terasic.com February 15, 2017 Chapter 1 Introduction This tutorial provides comprehensive information that will help you understand how to create a FPGA design and run it on your DE10-Standard development board. The following sections provide a quick overview of the design flow, explain what you need to get started, and describe what you will learn. D Deessiiggnn FFlloow w Figure 1-1 shows the FPGA design flow block diagram. The standard FPGA design flow starts with design entry using schematics or a hardware description language (HDL), such as Verilog HDL or VHDL. In this step, you can create a digital circuit that is implemented inside the FPGA. The flow then proceeds through compilation, simulation, programming, and verification in the FPGA hardware. Figure 1-1 Design Flow This tutorial guides you through all of the steps except for simulation. Although it is not covered in this document, simulation is very important to learn, and there are entire applications devoted to simulating hardware designs. There are two types of simulation, Functional and Timing Functional simulation allows you to verify that your code is manipulating the inputs and outputs appropriately. Timing (or post place-and-route) simulation verifies that the design meets timing and functions appropriately in the device.

www.terasic.com February 15, 2017 B Beeffoorree Y Yoouu B Beeggiinn This tutorial assumes the following prerequisites ■ You generally know what a FPGA is. This tutorial does not explain the basic concepts of programmable logic. ■ You are somewhat familiar with digital circuit design and electronic design automation (EDA) tools. ■ You have installed the Altera Quartus II 16.1 software on your computer. If you do not have the Quartus II software, you can download it from the Altera web site at www.altera.com/downloads. ■ You have a DE10-Standard Development Board on which you will test your project. Using a development board helps you to verify whether your design is really working. ■ You have gone through the quick start guide and/or the getting started user guide for your development kit. These documents ensure that you have:  Installed the required software.  Determined that the development board functions properly and is connected to your computer. Next step you should installed the USB-BlasterII driver, Plug in the 12-volt adapter to provide power to the board. Use the USB cable to connect the leftmost USB connector on the DE10-Standard board to a USB port on a computer that runs the Quartus II software. Turn on the power switch on the DE10-Standard board. The computer will recognize the new hardware connected to its USB port and Power on the board as shown in Figure 1-2, but it will be unable to proceed if it does not have the required driver already installed. The DE10-Standard board is programmed by using Altera USB-Blaster II mechanism. If the USB-Blaster II driver is not already installed, the Driver Software Installation in Figure 1-3 will appear.Click close.

www.terasic.com February 15, 2017 Figure 1-8 The driver is installed 11..11 W Whhaatt Y Yoouu W Wiillll LLeeaarrnn In this tutorial you will perform the following tasks: Create a design that causes LEDs on the development board to blink at a speed that is controlled by an input key—This design is easy to create and gives you visual feedback that the design works. Of course, you can use your DE10-Standard board to run other designs as well. For the LED design, you will write Verilog HDL code for a simple 32-bit counter, add a phase-locked loop (PLL) megafunction as the clock source, and add a 2-input multiplexer megafunction. When the design is running on the board, you can press an input switch to multiplex the counter bits that drive the output LEDs. Becoming familiar with Quartus II design tools—This tutorial will not make you an expert, but at the end, you will understand basic concepts about Quartus II projects, such as entering a design using a schematic editor and HDL, compiling your design, and downloading it into the FPGA on your DE10-Standard development board. Develop a foundation to learn more about FPGAs—For example, you can create and download digital signal processing (DSP) functions onto a single chip, or build a multi-processor system, or create anything else you can imagine all on the same chip. You don’t have to scour data books to find the perfect logic device or create your own ASIC. All you need is your computer, your imagination, and an Altera DE10-Standard FPGA development board.

www.terasic.com February 15, 2017 Chapter 2 Assign The Device You begin this tutorial by creating a new Quartus II project. A project is a set of files that maintain information about your FPGA design. The Quartus II Settings File (.qsf) and Quartus II Project File (.qpf) files are the primary files in a Quartus II project. To compile a design or make pin assignments, you must first create a project. 22..11 A Assssiiggnn TThhee D Deevviiccee 1. In the Quartus II software, select File > New Project Wizard.

Press the Esc key or click an empty place on the schematic grid to cancel placing further instances of this symbol. 19. Save your project regularly. Using Quartus Add a PLL IP There is a IP catalog which can easily customize and integrate IP cores into your project. Use the IP Catalog and parameter editor GUIs to select, customize, and generate files representing your custom IP variation. You can increase efficiency by using a megafunction instead of writing the function yourself. Altera also provides more complex functions, called MegaCore functions, which you can evaluate for free but require a license file for use in production designs. This tutorial design uses a PLL clock source to drive a simple counter. A PLL uses the on-board oscillator (DE10-Standard Board is 50 MHz) to create a constant clock frequency as the input to the counter. To create the clock source, you will add a pre-built IP core named Altera PLL. 1. Choose Tools > IP Catalog to automatically displays the IP cores available for your target device. Double-click any IP core name to launch the parameter editor and generate files representing your IP variation (see Figure 3-8).

You can add notes or information to the project as text using the Text tool on the toolbar (indicated with the A symbol). For example, you can add the label “OFF = SLOW, ON = FAST” to the KEY [0] input pin and add a project description, such as “My First FPGA Project.”

www.terasic.com February 15, 2017 33..33 A Assssiiggnn tthhee PPiinnss In this section, you will make pin assignments. Before making pin assignments, perform the following steps: 1. Choose Processing > Start > Start Analysis & Elaboration in preparation for assigning pin locations. 2. Click OK in the message window that appears after analysis and elaboration completes. To make pin assignments that correlate to the KEY[1:0] and CLOCK_50 input pins and LED[3..0] output pin, perform the following steps: 1. Choose Assignments > Pin Planner, which opens the Pin Planner, a spreadsheet-like table of specific pin assignments. The Pin Planner shows the design’s six pins. See Figure 3-32.

www.terasic.com February 15, 2017 Figure 3-32 Pin Planner Example 2. In the Location column next to each of the seven node names, add the coordinates (pin numbers) as shown in Table 3-1 for the actual values to use with your DE10-Standard board. Table 3-1 Pin Information Setting Pin Name FPGA Pin Location CLOCK_50 AF14 KEY[1] AK4 KEY[0] AJ4 LED[3] AD24 LED[2] AC23 LED[1] AB23 LED[0] AA24

www.terasic.com February 15, 2017 Double-click in the Location column for any of the seven pins to open a drop-down list and type the location shown in the table alternatively, you can select the pin from a drop-down list. For example, if you type F1 and press the Enter key, the Quartus II software fills in the full PIN_F1 location name for you. The software also keeps track of corresponding FPGA data such as the I/O bank and VREF Group. Each bank has a distinct color, which corresponds to the top-view wire bond drawing in the upper right window. See Figure 3-33. Figure 3-33 Completed Pin Planning Example Now, you are finished creating your Quartus II design! 33..44 C Crreeaattee aa D Deeffaauulltt TTiim meeQ Quueesstt SSD DC C FFiillee Timing settings are critically important for a successful design. For this tutorial you will create a basic Synopsys Design Constraints File (.sdc) that the Quartus II TimeQuest Timing Analyzer uses during design compilation. For more complex designs, you will need to consider the timing requirements more carefully. To create an SDC, perform the following steps:

www.terasic.com February 15, 2017 1. Open the TimeQuest Timing Analyzer by choosing Tools > TimeQuest Timing Analyzer. 2. Choose File > New SDC File. The SDC editor opens. 3. Type the following code into the editor: create_clock -name "CLOCK_50" -period 20.000ns [get_ports {CLOCK_50}] derive_pll_clocks derive_clock_uncertainty 4. Save this file as my_first_fpga.sdc (see Figure 3-34). Figure 3-34 Default SDC Naming the SDC with the same name as the top-level file except for the .sdc extension causes the Quartus II software to using this timing analysis file automatically by default. If you used another name, you would need to add the SDC to the assignments file list.

www.terasic.com February 15, 2017 Chapter 4 Compile and Verify Your Design After creating your design you must compile it. Compilation converts the design into a bitstream that can be downloaded into the FPGA. The most important output of compilation is an SRAM Object File (.sof), which you use to program the device. The software also generates other report files that provide information about your code as it compiles. 44..11 C Coom mppiillee Y Yoouurr D Deessiiggnn If you want to store .SOF in memory device (such as flash or EEPROMs), you must first convert the SOF to a file type specifically for the targeted memory device. Now that you have created a complete Quartus II project and entered all assignments, you can compile the design. In the Processing menu, choose Start Compilation or click the Play button on the toolbar. If you are asked to save changes to your BDF, click Yes. While compiling your design, the Quartus II software provides useful information about the compilation (see Figure 4-1).

www.terasic.com February 15, 2017 Figure 4-1 Compilation Message for project When compilation is complete, the Quartus II software displays a message. Click OK to close the message box. The Quartus II Messages window displays many messages during compilation. It should not display any critical warnings; it may display a few warnings that indicate that the device timing information is preliminary or that some parameters on the I/O pins used for the LEDs were not set. The software provides the compilation results in the Compilation Report tab as shown in Figure 4-2.

www.terasic.com February 15, 2017 Figure 4-2 Compilation Report Example 44..22 PPrrooggrraam m tthhee FFPPG GA A D Deevviiccee After compiling and verifying your design you are ready to program the FPGA on the development board. You download the SOF you just created into the FPGA using the USB-BlasterII circuitry on the board. Set up your hardware for programming using the following steps: a) Connect the power supply cable to your board and to a power outlet. b) For the DE10-Standard board, connect the USB-BlasterII (included in your development kit) to J13 and the USB cable to the USB-BlasterII. Connect the other end of the USB cable to the host computer. Refer to the getting started user guide for detailed instructions on how to connect the cables. c) Turn the DE10-Standard board on using the on/off switch.

Figure 4-7 Downloading Complete Congratulations, you have created, compiled, and programmed your first FPGA design! The compiled SRAM Object File (.sof) is loaded onto the FPGA on the development board and the design should be running. 44..33 V Veerriiffyy TThhee H Haarrddw waarree When you verify the design in hardware, you observe the runtime behavior of the FPGA hardware design and ensure that it is functioning appropriately. Verify the design by performing the following steps: 1. Observe that the four development board LEDs appear to be advancing slowly in a binary count pattern, which is driven by the simple_counter bits [26..23]. The LEDs are active high, therefore, when counting begins all LEDs are turned off (the 0000 state). 2. Press and hold KEY [0] on the development board and observe that the LEDs advance more quickly. Pressing this KEY causes the design to multiplex using the faster advancing part of the

www.terasic.com February 15, 2017 counter (bits [24..21]). 3. If other LEDs emit faintness light, Choose Assignments > Device. Click Device and Pin Options. See Figure 4-8. Figure 4-8 Device and Options Choose unused pins. Reserve all unused pins: Choose the As input tri-stated option. See Figure 4-9.
