摘要: A variable design tool utilizes memory units to determine at which point a design rule fails. The variable design tool can provide a bit map indicating the points of failures for particular rules. The bit map can also be utilized to determine misalignment errors. The memory cells, typically SRAM units are arranged in 4×4 matrices which are arranged in four 16×16 matrices.
