摘　　要：数字水印技术是一种重要的知识产权核(IP)保护技术,也是应用最广泛的IP核保护技术。介绍了常用的数字水印生成方法,分析了在FPGA设计的各个层面(软核、固核、硬核)的IP核数字水印技术。IP核保护数字水印技术可以分为附加保护技术、约束保护技术和检测技术,从附加和约束两个方面分析了水印嵌入技术,介绍了水印检测技术,分析了各种方法的原理和优缺点。从性能影响、资源开销、透明性、安全性、可信度等5个方面,对几种典型的水印技术进行评估比较,最后指出数字水印技术需要解决的问题和发展趋势。Digital watermarking is one of the most important and widely applied IP-cores protection technology.Some common digital watermarking generation methods are presented.IP digital watermarking techniques in the FPGA design flows（HDL,netlist,bitfile） are studied.Watermarking techniques include additive methods,constraint-based methods and identifying methods.The watermarking protection and detecting techniques are analyzed from two aspects,such as additive and constraint-based methods.And the advantages and disadvantages of these methods are presented.Several watermarking techniques are evaluated and compared in respect of performance,overhead,transparency,safety,authorship.Finally,the problem needs to be solved about the watermarking techniques and the prospects are presented.
