Securing FPGAs Made Simple
Secure FPGA development often feels like a maze. You juggle threats, IP, code, hardware. Miss one step, and your design is at risk. What if a single kit could guide you? That’s Microchip’s SmartFusion2 Security Evaluation Kit.
In this guide, we demystify security. You’ll learn about built-in crypto engines, a hardware root of trust, tamper detection and a cost-optimised SoC FPGA approach. We’ll walk you through setup, demos and best practices. Ready to start?

Why Security Matters in FPGA Designs
FPGA designs are everywhere. In network appliances, defence systems, IoT gateways. A single flaw can expose secret keys or backdoors. Pressure mounts fast. So security isn’t an afterthought. It’s front and centre.
Emerging Threats at the Edge
• Side-channel attacks on crypto modules
• Fault injection to disrupt boot logic
• Supply chain risks in IP cores
These threats evolve. Rapidly. You need tools that adapt.
IoT and Network Vulnerabilities
Edge devices connect to the cloud. Bad actors lurk. A compromised FPGA becomes a gateway. Not good. You need hardware-level safeguards. That’s where SmartFusion2 shines.
Introducing the SmartFusion2 Security Evaluation Kit
Microchip packed a lot into this board. It’s more than an FPGA. It’s a complete secure SoC solution. Ideal for proof-of-concepts and performance tests.
Key Features at a Glance
• Integrated Cortex-M3 CPU for real-time control
• Triple-speed Ethernet with MAC security
• Crypto engines: AES, SHA, RSA accelerators
• Built-in root of trust and secure boot
It’s all on one board. No add-ons. No guesswork.
Built-in Crypto Engines and Root of Trust
The hardware root of trust seeds every operation. You sign your firmware; the kit verifies at power-on. AES and SHA blocks speed up encryption. RSA offloads public-key maths. You focus on design. The kit locks down the rest.
Onboard Resources and Expandability
• Multiple GPIO banks for custom peripherals
• USB-to-JTAG interface for seamless programming
• PMOD connectors for add-on modules
• FMC connector for high-density I/O
Plug in shields or daughter cards. Scale as you need.
Getting Started: Hands-On with the Kit
No mysteries. No hours of reading. Here’s how to roll.
Unboxing and Setup
- Connect the USB-to-JTAG cable to your PC.
- Power the board via Micro-USB or an external supply.
- Open the status LEDs. They show power, programming and system health.
That’s it. You’re live.
Quick Start with Libero SoC
- Install Libero SoC from Microchip’s website.
- Open the “SmartFusion2 Security Demo” project.
- Hit “Build” and then “Program”.
You’ll see the demo blink LEDs, run crypto tests and log to a UART port. You’re up and running in minutes.
Best Practices for Secure FPGA Development
Security isn’t one and done. It’s a process. Follow these steps for robust designs.
Defining Your Threat Model
Ask: what can go wrong? List out:
• Physical attacks on board components
• Malicious firmware updates
• Eavesdropping on communication links
Clear scope. Less guesswork.
Leveraging Hardware IP
Use pre-verified IP blocks. They come with documentation and test benches. Less risk. Faster time to market.
Validating Security at Each Stage
• Unit test crypto functions in simulation
• Use formal analysis on sensitive logic
• Perform fuzz testing on interfaces
Test early. Test often.
