摘　　要：针对LUT型胚胎电子阵列功能分化方法的不足,提出了一种新型的LUT型胚胎电子阵列功能分化方法,根据目标电路的功能描述,通过前端综合、逻辑优化、逻辑映射、打包等操作,将目标电路转换为电子细胞为基本节点的电路形式,通过物理映射、基因库生成,将电路映射到阵列上,确定阵列中每个细胞的功能、连接,最终生成目标电路的基因库并确定每个细胞的表达基因,完成胚胎电子阵列的功能分化.该方法无需对计算过程中每一代电路进行功能评估,运算量小,计算速度快,为基于LUT型胚胎电子阵列的自修复电路应用提供了设计方法.最后,使用一个算例阐述了功能分化过程,并通过多个电路验证了该方法的分化速度.Aiming at the deficiency of the functional differentiation of LUT-based embryonics array,a novel functional differentiation method was proposed.Firstly,based on the functional description,the target circuit was converted to a new form with electronic cell as basic node through front synthesis,logic optimization,logical mapping and packing.Then,the circuit was mapped into embryonics array,and the function and connection of each electronic cell were determined through physical mapping process.At last,the genome was generated and the expressed gene of each electronic cell was confirmed with the genome generated process,and the functional differentiation of embryonics array was completed.The new functional differentiation method does not require the functional evaluation of each generation circuit,and the computational cost is reduced,the calculation speed is improved.The presented method provides a design method for the self-repair circuit application based on LUT-based embryonics array.The functional differentiation is described with an example,and the differentiation speed is verified through various circuits＇ functional differentiation.
