Microchip’s Libero SoC design suite (for FPGA, SoC FPGA, and PolarFire devices) typically requires a paid license for full features. However, free options are available for specific use cases:
If you are prototyping a design for an MPF100 PolarFire board or an IGLOO2 Nano board, you have nothing to pay. Libero Silver removes the financial friction from FPGA development, allowing you to focus on RTL design and embedded RISC-V software.
- Free (no-cost) edition: Microchip provides a no-cost edition of Libero with support for smaller device families and basic synthesis, simulation, and place-and-route flows. It’s intended for evaluation, learning, and small projects.
- Device-limited license: The free edition is typically limited by supported device families or device sizes (e.g., certain FPGA densities or specific product lines may require a paid license).
- Time- or feature-limited trials: Microchip sometimes offers trial licenses that enable full features for a limited time.
- Paid/professional licenses: Larger designs, advanced optimizations, higher-performance tools, or full device support require purchased licenses (node-locked or floating).
- Activation methods: Licenses are managed via Microchip’s licensing portal, using activation keys tied to host IDs or a license server for floating licenses.
- Redistribution & IP: Generated bitstreams and user-created IP are yours to use, but redistribution of the Libero tool itself is not permitted; check Microchip’s EULA for specifics on reverse engineering, redistribution, and IP ownership.
- Third-party IP/tools: Some flows rely on third-party IP or tools that have separate license terms (e.g., certain simulators or synthesis cores).
Microchip offers two types of no-cost licenses, though most designers will require the tier for actual hardware programming. Silver License (Recommended)
Enter Microchip Technology’s Libero SoC Design Suite—a powerful, feature-rich environment for designing with Microchip’s FPGA families (IGLOO, Fusion, ProASIC3, SmartFusion, and PolarFire). Unlike many competitors that gate critical features behind paywalls, Microchip offers a robust free license model that allows you to develop, simulate, and even synthesize designs without paying a cent.
Common Misconceptions Addressed
"Free means no technical support."
False. Microchip provides community forums and extensive documentation. While priority support is for Gold licensees, Microchip’s FAEs (Field Application Engineers) often answer free user questions, especially if a design is likely to lead to production.
