摘　　要：反熔丝FPGA制造困难且多用在特殊用途领域,因此有关其位流文件的研究很少.本文首先介绍了反熔丝FPGA及FPGACAD软件流程,接着描述了反熔丝FPGA具体结构并通过一个具体例子说明了如何配置反熔丝FPGA,然后讨论了反熔丝FPGA的编程方法,由此引出了位流文件的格式和反熔丝单元编程信息格式,最后提出了反熔丝FPGA位流文件生成算法并在实验平台实现了该算法.Since Antifuse--FPGA is only used in specified fields and it＇s difficult to manufacture, researches about bit--stream generation of Antifuse--FPGA are seldom done before. Basic knowledge about Antifuse--FPGA and the flow of FPGA CAD tool were introduced firstly. Then detail architecture of Antifuse--FPGA was described and methods of configuring Antifuse--FPGA were also elaborated through a real example. Afterward this paper discussed the way to configure Antifuse--FPGA, and by doing that the pattern of bit--stream file and its basic unit, containing information of Antifuse which was to be programmed, was deduced. At last, the algorithm of generating bit--stream file of Antifuse--FPGA was concluded and it was realized on the experimental platform.
