Abstract

The new approach to patching circuit design that allows masking any logical gate faults of combinational circuit (combinational part of sequential circuit) C is considered. It is supposed that only one gate may be fault. There are reserved Configurable Logic Blocks (CLBs) based on Look Up Tables (LUTs) that may mask a gate fault being included into the circuit through Multiplexer (MUX). The suggested approach to patching circuit design in contrast with currently in use allows keeping performance of a fault free circuit. It is suggested to include MUXs in those internal poles of circuit C that may have hard detectable faults. Experimental results showed that masking LUT based circuits are as a rule, rather simple.
基于预留clb的修补电路设计
提出了一种新的补片电路设计方法,该方法可以屏蔽组合电路(顺序电路的组合部分)C的任何逻辑门故障。假定只有一个门可能有故障。有保留的基于查找表(lut)的可配置逻辑块(clb),可以屏蔽通过多路复用器(MUX)包含在电路中的门故障。与目前使用的方法相比,建议的修补电路设计方法允许保持无故障电路的性能。建议在C电路可能存在难以检测的故障的内部极中包含mux。实验结果表明,基于掩模LUT的电路通常相当简单。
