XC7A200T: Best Artix-7 Development Boards

Introduction to Artix-7 FPGA Development Boards

After spending over a decade working with FPGAs in production environments, I’ve tested nearly every Xilinx Artix-7 development board on the market. Whether you’re prototyping a new design, teaching digital logic courses, or building a commercial product, choosing the right Artix-7 development board can make or break your project timeline.

The AMD (formerly Xilinx) Artix-7 family sits in a sweet spot for most designers. Built on 28nm process technology, these FPGAs deliver excellent performance-per-watt while keeping costs reasonable. The flagship XC7A200T packs 215,360 logic cells, 740 DSP slices, and 13Mb of block RAM – enough horsepower for serious signal processing, video applications, and embedded systems.

In this guide, I’ll break down the most popular Artix-7 boards including the Arty A7, Basys 3, Nexys A7, and several alternatives. My goal is to give you the practical insights you need to pick the right board for your specific application – not just marketing specs from datasheets.

Why Choose a Xilinx Artix-7 Development Board?

The Artix-7 series represents AMD’s cost-optimized FPGA line, targeting applications where Spartan-7 falls short on resources but Kintex-7 would be overkill. Here’s why so many engineers gravitate toward the Artix-7 family:

• 50% lower power consumption compared to the previous 45nm generation (Spartan-6)
• 35% cost reduction versus equivalent Spartan-6 designs
• Up to 6.6 Gbps transceivers for high-speed serial interfaces
• MicroBlaze soft processor support with 1,066 Mb/s DDR3 capability
• Unified architecture across all 7-series devices for easy design migration

From a PCB design standpoint, the Artix-7 devices come in compact BGA packages that work well in space-constrained applications. The XC7A35T starts at 236 balls, while the larger XC7A200T is available in packages up to 1156 balls depending on your I/O requirements.

Understanding Artix-7 FPGA Variants: XC7A35T vs XC7A100T vs XC7A200T

Before diving into specific boards, it’s worth understanding what you get with each Artix-7 device. Most development boards use one of three main variants:

Basys 3 Artix-7 FPGA Trainer Board: Best for Learning

The Basys 3 FPGA board from Digilent remains the gold standard for FPGA education. Built around the XC7A35T-1CPG236C, this Basys 3 Artix-7 trainer packs everything beginners need without overwhelming complexity.

Basys 3 Key Features

• FPGA: XC7A35T-1CPG236C with 33,280 logic cells
• On-board I/O: 16 switches, 16 LEDs, 5 push buttons, 4-digit 7-segment display
• Connectivity: VGA output, USB-HID port, 3 Pmod connectors
• Clock: 100 MHz oscillator
• Price: ~$149 (academic pricing available)

Basys 3 Practical Assessment

From my experience using the Basys 3 in lab environments, the abundant built-in peripherals eliminate the need for external hardware during early learning stages. Students can immediately implement VGA drivers, state machines with switch inputs, and multiplexed display controllers without wiring anything up.

The main limitation? No external DDR memory. This restricts more advanced applications like video frame buffering or running larger MicroBlaze applications. If you’re planning to move beyond basic digital logic into embedded systems, you’ll eventually outgrow this board.

Arty A7: The Maker’s Choice for Artix-7 Development

The Arty A7 represents Digilent’s answer to makers and hobbyists who want more capability than educational boards provide. Available in two variants (A7-35T and A7-100T), this board bridges the gap between learning tools and production-ready development platforms.

• User I/O: 4 switches, 4 buttons, 4 RGB LEDs, 4 green LEDs
• Price: ~$129 (35T) / ~$249 (100T)

Arty A7 vs Basys 3: Engineering Considerations

The 256MB DDR3L on the Arty A7 changes everything. You can now run substantial MicroBlaze or RISC-V soft processor designs with real application memory. The Ethernet port opens doors for networked embedded systems that simply aren’t possible on the Basys 3.

However, the Arty A7 sacrifices on-board switches and displays. If you’re teaching basic digital design concepts, the Basys 3’s abundant user I/O is more pedagogically useful. The Arty A7 shines when you’re building actual projects where you’ll eventually connect external interfaces anyway.

Nexys A7: Full-Featured Academic Development Platform

The Nexys A7 (formerly Nexys 4 DDR) combines the best of both worlds – abundant on-board peripherals like the Basys 3, plus DDR memory and Ethernet like the Arty A7. It’s positioned as the premium academic platform for serious ECE curriculum.

Nexys A7 Feature Set

Frequently Asked Questions About Artix-7 Development Boards

Q1: What’s the difference between Artix-7 and Spartan-7 FPGAs?

The main differences are resource count and high-speed transceiver availability. Artix-7 offers more logic cells (up to 215K vs 102K), more block RAM, and includes GTP transceivers for high-speed serial interfaces. Spartan-7 is designed for cost-sensitive applications where these features aren’t needed. For most learning and development purposes, Artix-7 provides more headroom.

Q2: Can I use the free Vivado edition with all Artix-7 boards?

Yes, the Vivado Standard Edition (formerly WebPACK) supports all Artix-7 devices at no cost. This includes full synthesis, implementation, simulation, and debug capabilities. The paid Enterprise Edition is only needed for UltraScale+ devices or specific advanced features.

Q3: Is the Basys 3 good enough for learning MicroBlaze?

You can run basic MicroBlaze designs on the Basys 3, but the lack of external DDR memory severely limits practical applications. The on-chip block RAM provides only about 90KB for both code and data. For serious embedded development, the Arty A7 or Nexys A7 with external RAM is a much better choice.

Q4: What programming languages work with Artix-7 boards?

VHDL and Verilog are the primary hardware description languages supported by Vivado. SystemVerilog is also supported for both design and verification. For embedded software development with MicroBlaze or RISC-V, you’ll use C/C++ through the Vitis development environment. High-level synthesis (HLS) allows C++ to be compiled directly to RTL.

Q5: How long does it take to compile an Artix-7 design?

Compile times vary dramatically based on design complexity and your computer specs. A simple LED blinker might take 2-3 minutes. A full MicroBlaze system with peripherals can take 15-30 minutes. Large XC7A200T designs approaching full utilization may take an hour or more. SSDs and multiple CPU cores significantly improve synthesis and implementation times.
