The Icicle Kit is based on Microchip’s PolarFire SoC (MPFS250T-FCVG484EES), which is a system-on-chip that combines the state-of-the-art PolarFire FPGA with a five-core RISC-V microprocessor subsystem by SiFive.
To quote the official PolarFire SoC documentation:
The PolarFire® SoC FPGA family delivers an unparalleled combination of low power consumption, thermal efficiency and defense grade security for smart, connected systems.
It’s the first system on chip (SoC) field-programmable gate array (FPGA) with a deterministic, coherent RISC-V CPU cluster and a deterministic L2 memory subsystem enabling Linux and real-time applications.
Built on the award-winning, mid-range, low power PolarFire FPGA Architecture, PolarFire SoC devices deliver up to 50% lower power than alternative FPGAs, span from 25k to 460k logic elements (LEs) and feature 12.7G transceivers.
The unique architecture of the PolarFire SoC combines the power of RISC-V and Linux with the determinism needed for real-time hardware applications. See Microchip’s PolarFire SoC brochure and overview for more information.
The Mi-V ecosystem brings together tools and vendors tailored for the PolarFire SoC, including:
Developing on the PolarFire SoC Icicle kit requires a Libero Silver license, which is free of charge and valid for one year. Once that license has expired, you will be able to generate a new license each year for free.
Linux development on the Icicle Kit does not require any closed source tools or familiarity with FPGA development tools. Here’s how to get started quickly:

That’s it! You are now logged into Linux running on the Icicle Kit.
Icicle Kit is an evolution of HiFive Unleashed by SiFive and the accompanying HiFive Unleashed Expansion Board by Microchip. We worked closely with SiFive to integrate their RISC-V cores into PolarFire SoC and consolidate everything onto a single board.
