Xilinx Design Linking License «2026»

Date: October 2023 (Updated for context through 2025 practices) Subject: Licensing Mechanisms for Design Linking in Xilinx (AMD) FPGAs Audience: FPGA Design Engineers, Hardware Managers, IP Integrators, Technical Procurement 1. Executive Summary The Xilinx Design Linking License (often referred to as the IP Linking License or Design Linking License within Vivado) is a critical, yet often misunderstood, software entitlement. Unlike device-locked node-locked licenses or standard floating feature licenses for synthesis/implementation, the Design Linking License specifically governs the aggregation and binding of multiple third-party and Xilinx LogiCORE IP blocks into a single design netlist.

| License Tier / Feature | Includes Design Linking? | Typical User | |------------------------|--------------------------|---------------| | (Free) | No | Small devices, limited IP | | Vivado HL Design Edition (Node-locked) | No | Individual designer, single IP | | Vivado HL System Edition (Floating/Node) | Yes (Full linking) | Team using multiple Xilinx IP | | Vivado Enterprise Edition | Yes (Advanced linking + PR) | Large teams, complex subsystems | | Vitis Unified Platform (Standard) | Limited (only AMD IP linking) | AI/ML & embedded software | | Vitis Embedded Edition | Yes (for MicroBlaze + peripherals) | Embedded FPGA developers | xilinx design linking license

Before starting a block design with two or more IP cores (especially from different vendors or encrypted), verify with lmstat that your license server provides design_linking . Otherwise, expect link-time errors and redesign delays. End of Report Date: October 2023 (Updated for context through 2025
