摘要
针对高可靠性领域和复杂环境对大规模反熔丝FPGA器件的迫切需求,设计了一种新的用于反熔丝FPGA的可动态配置IO接口电路。该IO接口电路具有宽的输入输出电压范围,能实现多驱动调节,支持一系列不同电平模式。通过对反熔丝单元进行编程配置,该IO接口电路可兼容多种IO标准,内核电压为2.5V,端口电压可在3.3V与5V之间转换。仿真与测试结果表明,该IO接口电路满足设计要求,接口速度优于国外同类产品。
A new dynamically reconfigurable IO circuit for anti-fuse FPGA was designed to meet the requirements of large-scale anti-fuse FPGA devices in high reliability and complex environment.The IO circuit featured a wide range of input and output voltages.It achieved multi-drive adjustment,and could support a series of different voltage modes.The proposed circuit could be compatible with multiple IO standards,having achieved a core voltage of 2.5 Vand a port voltage of 3.3 V/5 V which was converted through the programmable configuration of anti-fuse unit.The simulation and tested results showed that the design of the IO circuit was effective and its interface speed was superior to the foreign similar products.
