【摘要】 针对具体的目标数字电路和FPGA(Field programmable Gate Array)结构特点,结合染色体直接编码方法,用Handel-C语言对基于EHW(Evolvable Hardware)的目标数字电路进行描述,在计算机上进行仿真。CeloxicaDK2设计工具将Handel-C源程序编译成能直接针对FPGA目标的网表(Netlist),最终利用FPGA布线工具下载到FPGA上实现目标数字电路功能,且该电路系统具有一定的自检测功能。同时解决了基于EHW的目标数字电路在硬件实现过程中存在的几个关键性问题,从而确保在FPGA上得以顺利实现基于EHW的目标数字电路。本文以四选一数据选择器作为目标数字电路。更多还原

【Abstract】 According to the target digital circuit and the structural character of FPGA(Field programmable Gate Array),this paper was adopted direct code by chromosome.The target digital circuit based on EHW could be described by Handel-C language.Handel-C program was simulated in the computer.Celoxica DK2 Design Suite could compile the source program of Handel-C directly into a Netlist of the target FPGA.The target digital circuit based on EHW could be implemented by the FPGA route tools in the FPGA at last and had some more self-detecting capability.At the same time,some key problems had been resolved in the process of hardware implementation of the target digital circuit based on EHW.Thus the target digital circuit based on EHW could be implemented all right in the FPGA.This paper used six-multiplexor as the target digital circuit.更多还原
