为有效划分低可测性模拟电路中的模糊组和正则模糊组,提出一种新的确定线性组合矩阵最简形式的方法。通过一个benchmark电路验证该方法仅需对被测电路的可测性矩阵进行一次QR分解和较少次数的矩阵运算;避免了组合搜索算法的搜索时间与被测元件参数的数目成几何级数增长,减小了计算处理的复杂度。
In order to effectively classify fuzzy groups and regular fuzzy groups in low-testability analog circuits, a new method of determining the simplest form of linear combination matrix is proposed. A benchmark circuit is used to verify that this method only needs to perform a QR decomposition and a matrix of fewer matrices on the measurable matrix of the circuit under test. This avoids the geometric progression of the search time of the combined search algorithm and the number of measured components , Reducing the computational complexity.
