Microchip’s Libero SoC (and related Libero IDE tools) are Microchip’s FPGA/SoC design suites for their PolarFire, SmartFusion2, and IGLOO2 families. Licensing looks like this in practice:
Microchip Technology's decision to make the Libero software license-free is a significant move that is expected to have a major impact on the industry. The license-free offering means that users can download and use the software without incurring any licensing fees. This move is expected to benefit small and medium-sized enterprises, startups, and hobbyists who may not have had access to such powerful design tools due to cost constraints.
To make sure I give you the right guide, could you clarify which of these you are looking for?
a device. It is designed for evaluating the software's capabilities and device fit before purchasing a paid Gold or Platinum license. Key Supported Devices (Silver License)
Designing with FPGAs and SoCs requires high-performance software, and for Microchip’s portfolio, that software is the Libero SoC Design Suite. While professional EDA tools often come with high price tags, Microchip provides free license options—specifically the Silver and Evaluation tiers—to support students, hobbyists, and professional engineers working on specific device families. Understanding the Free "Silver" License
Evaluation/Trial License: A temporary, all-access license used to test high-end features or larger devices for 30 days.
