总线胚胎电子细胞阵列中空闲细胞数目优选

摘要

胚胎仿生硬件技术为高可靠性大规模集成电路系统设计提供了一种新思路.在确定规模的总线胚胎电子细胞阵列中,为兼顾阵列的硬件资源消耗和可靠性,本文提出了一种阵列内空闲细胞数目的优选方法.基于多态系统可靠性理论,利用通用生成函数建立阵列的可靠性模型. 以阵列 MOS ( Metal Oxide Semicon-ductor)管消耗数目为硬件资源消耗衡量指标,建立阵列的硬件资源消耗模型.基于阵列的可靠性和硬件资源消耗模型,在一定设计约束条件下,对阵列内空闲细胞数目进行优选.仿真实验和分析表明,该方法能够根据阵列设计要求选择最合适的阵列内空闲细胞数目,同时,解决了胚胎电子细胞阵列中空闲细胞数目选择依靠经验的问题.%Embryonic bio-inspired hardware technology provides a new idea for designing large scale integrated cir-cuit with high reliability. In the bus-based embryonic electronic cell array (BEECA) with determined scales,an idle cells op-timum selection method is proposed,which finds a balance between hardware resource consumption and reliability. Based on the multi-state system reliability theory,a universal generating function (UGF) is used to establish BEECA reliability mod-el. The consumed number of MOS (Metal Oxide Semiconductor) transistors is used to measure BEECA hardware resource consumption,and BEECA hardware resource consumption model is established. Based on the established reliability model and hardware resource consumption model,the unoccupied cell number in the array is selected under the constraints of the design. The simulation experiment and analysis indicate that the proposed design can optimize the selection,and in the mean-while the selection can avoid the dependence on the experiences.
