Abstract： As the complexity of System-on-Chip (SoC) design continues to increase, the efficient reuse of Intellectual Property (IP) core has become critical for shortening design cycles. However, IP delivery packages typically contain multiple heterogeneous file formats, and traditional file directory management suffers from decentralized storage and poor retrievability, while commercial tools impose prohibitive licensing costs. To address these challenges, this paper designs and implements an IP core data sharing platform based on a metadata model. The platform adopts a hybrid storage architecture with metadata and file objects separated, linking structured attributes to physical files through unique identifiers to enable retrievable modeling of IP core data. A client-side intelligent preview engine is constructed to support zero-download in-browser rendering, including syntax highlighting for Verilog/VHDL source code and PDF document rendering. Experimental results demonstrate that the platform effectively resolves the engineering challenges of decentralized storage and difficult retrieval of IP core data, providing a low-cost, high-reuse-efficiency IP core management solution for System-on-Chip development.
