Detailed and precise hierarchical design planning is essential to achieving closure on large designs. In this article we describe a new hierarchical design flow and its usage on a 3 million-gate chip.

A lithographic (litho) hotspot is a defect on a wafer that is created during manufacturing by a combination of systematic process variation and resolution enhancement technology (RET) limitations.

Pattern matching is best known for its use in detecting lithographic hotspots, but it’s also widely used across all physical verification flows, and has expanded into design-for-manufacturing (DFM) ...

An internal computer aided design (CAD) or design services engineer is responsible for delivering efficient, robust and high-quality design flow solutions. The design flow on a day-to-day basis keeps ...
