However, when deciding which parts of a design to redact, there are a number of practical issues that designers need to consider, including area and timing overheads, as well as security factors. Adapting an open-source FPGA fabric generation flow, we perform a case study to explore the trade-offs when redacting different modules of open-source intellectual property blocks (IPs) and explore how different parts of an eFPGA contribute to the security. We provide new insights into the feasibility and challenges of using eFPGA-based redaction as a security solution.","url_abs":"https://arxiv.org/abs/2110.13346v1","url_pdf":"https://arxiv.org/pdf/2110.13346v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"exploring-efpga-based-redaction-for-ip","repo_url":"https://github.com/nyu-hardware-security/fpga-fabrics-for-redaction-iccad","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
