April 1, 2004 -- As engineers target processes at 130 nm or smaller, they need more tools and methods to verify that a design is manufacturable with a reasonable yield. These processes form a category called DSM (deep-submicron) manufacturing, which also encompasses the methods and tools that engineers need for such designs. Even the most elegant design is worth nothing if you cannot manufacture it and sell it to generate income and profit. Therefore, engineers are looking for guidelines and safeguards that increase their probability of success. Two methods have joined DFT in providing guidance to designers: DFM (design for manufacturing) and DFY (design for yield). Both segments of the EDA market are growing rapidly, but the new tools require more seasoning before a complete solution will become available.
