| | Integrated Circuit Development |
 | | The disadvantage of this semi-custom approach is that the circuit is not necessarily optimized for speed and density; however, the advantage is that once the logic gates have been verified, the time and cost required to design a new function or modify an existing design is greatly reduced in comparison to the full custom approach. | | | Once the simulated results have been verified, the tools are used to develop additional integrated circuits, with a much greater chance of first pass success than would be the case without any ability to predict the outcome of the design process. | | | Figures IC-8 and IC-9 illustrate the speed-power performance of a number of different device types for known analog and digital circuits for which considerable test data exists in our laboratory for a number of device technologies, with the results from the low bandgap transistors developed from simulations. |

| | The development and optimization of these processes may be a well-guarded trade secret of the original integrated circuit manufacturer. | | | For example, a MOSFET containing integrated circuit has a substrate level topography, a gate level topography, and plural upper level metal interconnection level topographies. | | | The computer generated layout can be developed faster than reverse engineering a chip. |

| | Remote plotting of integrated circuit layout in a network computer-aided design system - Patent 5128878 |
| | Client workstations are programmed to create plot requests from data created in a computer aided integrated circuit design and layout application. | | | A remote plotting system and method is implemented in a network of computer workstations whereby a designated computer functions as a plot server. | | | Accordingly, a need remains for an improved method and system for rasterizing, spooling and plotting graphical hardcopy of integrated circuit designs captured on client workstations which would allow the user to continue other tasks while the time and resource consuming processes of rasterization and hardcopy plotting run uninterrupted. |

| | As integrated circuit mask layouts inexorably increase in complexity, the fundamental limitations of the industry standard GDSII file format have become a bottleneck. | | | A major weakness of the GDSII format is inefficient data representation, which leads to very large files. | | | The format makes use of a number of techniques to this end. |

| | What is Optimization? |
| | The user does not particularly want to optimize anything so there is no reason to define an objective function. | | | In some cases (for example, design of integrated circuit layouts), the goal is to find a set of variables that satisfies the constraints of the model. |
