$GTCH During the physical design process a computer program is processing the microchip database, which is a huge size data. Typical processing of an advanced nanometer IC data, preparing it for physical verification, is a major time-consuming process. During this process the IC’s data is read and the program learns about the geometric shapes, which is called the mask layout. A set of mathematical algorithms then process this data to verify that all geometrical, electrical and DFM (Design For manufacturing) rules are met. The database engine is a key factor to the entire process performance.
