Special attention is paid to its structure and the influence of longitudinal and transverse end effect. The distribution of electromagnetic field of PMLSM can be obtained directly and promptly by using FFT algorithm. It can also be used for the analysis of other LSM.展开更多

In a GID-testable twodimensional array, the primary x and y outputs are organized into groups and every group has more than one output. This is similar to the GI-testable arrays. However,GID-testability not only ensures that identical test responses can be obtained from every output in the same group when an array is fault free, but also ensures that at least one output has different test responses (from the other outputs in a group) when a cell in the array is faulty Therefore, all faults can be detected under the assumption of a single faulty cell model. It is proved that an arbitrary two-dimensional iterative array is GID-testable if seven x-states and seven y-states are added to the original flow table of the basic cell of the array.GID-testability simplifies the response verification of built-in-self testing in a way similar to PL- and GI-testability[6-9]. Therefore, it is suitable for BIST design.展开更多
