Creating Your First FPGA Design

Writing HDL Code

You begin your first fpga design by making HDL code. HDL means hardware description language. You can pick VHDL or Verilog for your rtl design. Good rtl coding helps your fpga use less power and work well. Here are some tips for writing rtl code that works well and can be made into hardware:

1. Keep your rtl design simple. Do not use hard combinational logic.

2. Share resources when possible. This saves DSP slices.

3. Use edge-triggered flip-flops instead of latches.

4. Always set reset conditions for your registers.

5. Add parameters or generics to make your rtl design flexible.

6. Break long logic into smaller pipeline stages for better speed.

7. Use pipeline registers to help with delays.

8. Put logic into LUTs and use BRAM for big data.

9. Use DSP blocks for math jobs.

10. Check timing reports to find and fix slow parts.

Tip: Clean and simple rtl design makes it easier to find bugs and helps your fpga run faster.

Simulation Basics

Before you put your rtl design on an fpga, you need to test it. Simulation lets you see if your rtl code works right. Vivado has a built-in simulator, but you can use other tools that work with xilinx fpgas:

• Aldec Active-HDL and Riviera-PRO

• Cadence Xcelium Simulator

• Siemens ModelSim and Questasim

• Synopsys VCS

• AMD Vivado Simulator

You write testbenches to check your rtl design. Simulation helps you find mistakes early and saves time.

Synthesis and Implementation

After you finish simulation, you move to synthesis and implementation in vivado. Here are the main steps:

1. Synthesis: Change your rtl code and rules into a netlist using the 'Run Synthesis' button in vivado.

2. Implementation: Put your rtl design onto the fpga by running 'Run Implementation' in vivado.

3. Generate Bitstream: Make a .bit file for your fpga using 'Generate Bitstream' in vivado.

4. Download Bitstream: Program your fpga board with the Hardware Manager in vivado.

Vivado helps you with each step. You can look at reports and fix problems before you program your xilinx fpga.

Programming and Testing Your Xilinx FPGA

Generating Bitstreams

After you finish your design in Vivado, you need to create a bitstream file. This file tells the fpga how to work. Vivado makes this process simple. You just click the "Generate Bitstream" button in the Vivado workspace. The tool will check your design and then build the bitstream. Vivado also creates SVF files. These files help with programming the fpga using tools like XJTAG. You can use the SVF file with the RUNSVF function if you know the device reference for your xilinx fpga. Bitstreams and SVF files are both important for getting your design onto the board.

Programming the Board

Once you have your bitstream, you can start programming the fpga board. Vivado gives you a Hardware Manager to help with this step. You connect your board to your computer with a USB or JTAG cable. Then, you open the Hardware Manager in Vivado and select your device. You load the bitstream file and click "Program". This sends your design to the fpga.

You can also use command-line tools for programming. Here are some reliable steps:

1. Build a bitstream with the test ROM for your board:

   cd $REPO_TOP
   ./bazelisk.sh build //hw/bitstream/vivado:fpga_${BOARD}_test_rom
   
   

2. Build a bitstream with the ROM for your board:

   cd $REPO_TOP
   ./bazelisk.sh build //hw/bitstream/vivado:fpga_${BOARD}_rom_with_fake_keys
   
   

3. Flash the bitstream onto the fpga using opentitantool:

   cd $REPO_TOP
   ./bazelisk.sh run //sw/host/opentitantool -- fpga load-bitstream $(ci/scripts/target-location.sh //hw/bitstream/vivado:fpga_${BOARD}_rom_with_fake_keys)
   
   

Programming the fpga is a key step. You must make sure the bitstream matches your board and your design.

Debugging Tools

You may find problems after programming the fpga. Vivado gives you strong debugging tools to help. You can use the Integrated Logic Analyzer (ILA) core from the IP Catalog. This tool lets you see signals inside your fpga while it runs. You can also use the Mark Debug feature in Vivado. This feature helps you watch certain signals and find bugs faster.

Tip: Use the ILA core to check your design in real time. This makes it easier to fix problems and improve your xilinx fpgas projects.

Vivado’s debugging tools help you test, find errors, and make your fpga design better. You can solve most issues without extra hardware.
