On GID-Testable Two-Dimensional Iterative Arrays

A new approach is presented for easily testable two-dimensional iterative arrays.It is an improvment on GI-testability (Group Identical testability) and is referred to as GID-testability (Group Identical and Different testability). 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 out…
