How to use Artix-7 AMD Xilinx100t vivado synthesis

To use the Xilinx Artix-7 FPGA (e.g., XC7A100T) with Vivado for synthesis, you need to follow a structured process involving project setup, HDL coding, synthesis, implementation, and bitstream generation. Here's a step-by-step guide for beginners or intermediate users:

✅ Requirements

• Vivado Design Suite (Download from AMD/Xilinx website)

• A supported Artix-7 board (e.g., Digilent Nexys A7 with XC7A100T chip)

• Basic knowledge of Verilog or VHDL

Step-by-Step Vivado Synthesis for Artix-7 XC7A100T

 1. Launch Vivado and Create a Project

1. Open Vivado.

2. Click Create New Project.

3. Enter a project name and directory.

4. Choose RTL Project (don’t check "Do not specify sources").

5. Add your HDL files (Verilog or VHDL).

6. Select the FPGA part:

• Family: Artix-7

• Package: CSG324 (common for many boards)

• Speed grade: -1

• Part: xc7a100tcsg324-1

• For Artix-7 XC7A100T:

 2. Write or Add Your HDL Code

Example (Verilog) – A simple LED blinker:

verilog

module led_blinker(
    input clk,           // Clock input
    output reg led       // LED output
);

reg [23:0] counter;

always @(posedge clk) begin
    counter <= counter + 1;
    if (counter == 24'd10000000)
        led <= ~led;
end

endmodule

 3. Set Constraints

You need an XDC (Xilinx Design Constraints) file to map logical signals to FPGA pins.

Example:

xdc

## Clock input
set_property PACKAGE_PIN E3 [get_ports clk]
set_property IOSTANDARD LVCMOS33 [get_ports clk]

## LED output
set_property PACKAGE_PIN H17 [get_ports led]
set_property IOSTANDARD LVCMOS33 [get_ports led]

Pin names depend on your board. Refer to the board’s User Manual or Master XDC File.

 4. Run Synthesis

1. Click Run Synthesis in the Flow Navigator.

2. Vivado will:

• Parse your code

• Optimize logic

• Generate RTL netlist

If it completes successfully, continue.

 5. Run Implementation

1. Click Run Implementation.

2. Vivado places and routes your design into the FPGA's fabric.

3. Review the timing summary to ensure constraints are met.

 6. Generate Bitstream

1. Click Generate Bitstream.

2. After generation, Vivado produces a .bit file (used to configure the FPGA).

 7. Program the FPGA (Optional)

If you have a development board connected:

1. Open Hardware Manager.

2. Connect to the board via USB/JTAG.

3. Program the FPGA with the .bit file.

 Tips

• Always verify your pin locations with the board’s reference manual.

• Use simulation (with Vivado’s built-in simulator or ModelSim) before synthesis.

• Use IP Integrator for complex systems like MicroBlaze or AXI-based designs.
