摘要
设计了一种具有故障自诊断和自修复能力的可重构阵列单元结构.在功能细胞单元内部实现分布式的故障自诊断,在测试到故障后,可以自主地将距故障单元最近的空闲单元进行替换,接着自动取消受故障影响的线网,并在新的布线端点间对这些线网重新布线.以4位并行乘法器为例,实验结果证明了可重构单元阵列的故障自修复能力,并验证其重构时间较短且可靠性较高.
A self-reconfigurable array cell structure with the ability of self-testing and self-repairing is presented.The distributed fault self-diagnosing can be achieved in the function cell unit.When the fault is tested,the nearest spare cells can automatically replace the faulty cells,cancel the nets which effected by fault automatically,and reroute these nets between the new endpoints.A 4-bit parallel multiplier is chose as an example.The experiment result demonstrates self-repairing ability of self-reconfigurable cell array,and testify it requires short reconfiguration time and improves the reliability.
