如何提高FPGA产品的保密性

vhe1981
vhe1981 over 15 years ago
Actel有些FPGA有采用熔丝烧写,而且有知识产权保护技术。好像lattice也有商业级的XPFA,就是将sram嵌入到fpga中,保密性非常好的,就是稍微贵了一些,不过比起Altera,Xilinx好像也有一下高安全级别的产品,应该是很便宜了。Actel的proASIC plus系列规模和sram相当,最大有100万门。就是价格贵了些。而且我们的产品着急上市,也来不仅换芯片,不过建议以后大家用的时候可以考虑一下.Actel的ProasicPlus系列保密性高可惜其结构太简单了每个LogicTitle仅仅十个D触发器,连个LUT也没有.ProAsicPlus 是不是有点像CPLD的结构。可能flash的工艺实现LUT很难吧,没有SRAM灵活。
