The "Microchip Libero license free" option is not a marketing gimmick; it is a fully functional, professionally-capable FPGA toolchain available at zero cost. Whether you are a student learning digital design, a researcher prototyping a clever algorithm, or a startup building a low-volume industrial controller, the free license removes the financial barrier to entry.
This is not a demo or a trial. It is a for specific use cases. Here is exactly what you get and, crucially, what you don't.
| Vendor | Free Tool | Device Limits | Duration | |--------|-----------|---------------|----------| | | Libero Silver | IGLOO2/SF2 up to 25K LEs, PolarFire up to 50K? | Perpetual | | Xilinx | Vivado WebPack | Up to 128K LEs (Artix-7, Zynq-7000 limited) | Perpetual | | Intel | Quartus Prime Lite | Up to 250K LEs (Cyclone IV, V, 10) | Perpetual | | Lattice | Radiant Free | Up to 100K LEs (CrossLink, Certus) | Perpetual |
Microchip does not "nerf" the toolchain for free users. Here is the feature set included in the no-cost license:
Pro Tip: Do not change your PC’s network adapter or motherboard, as that changes the Host ID and breaks the license.
