The extension of the expert design based layout generator, LGen, is examined in detail.
These extensions include the generator being ported to the GNU/Linux platform as well as the
addition of two analog circuit layout generators to the system.
The future of layout generation is discussed. It has been proven in the industry that fully
automated approaches to layout generation in digital circuits, given broad algorithmic or netlist
specifications, is possible and practical. Despite many attempts in academia, this approach has
not been proven in the analog domain. An expert design based layout generator that adequately
captures expert design in a reusable, platform and process independent way, is the answer.
LGen is used in the layout design of a low noise, low power switched capacitor filter. Its
circuit design is also discussed in detail.
The future of expert based layout generators is believed to be in constraint based geometry
databases. Such a layout generator, properly implemented, would resolve complex layout
interconnectivity automatically, simplifying layout design.
