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.

The level of automation applied to analog design has never approached the level enjoyed by digital designers. For years designers have iterated through schematic entry, physical layout, parasitic ...

The effort in designing analog/mixed-signal (AMS) integrated circuits is characterized by the largely manual work involved in the design of analog cells and their integration into the overall circuit.
