Tool Integration and Enhancement for Standard Cell Designs.

摘要

Application-specific integrated circuits designed using standard cells minimize the training and development time for engineers while maximizing the likelihood of obtaining functional silicon. By integrating and enhancing existing computer-aided design tools, it is now possible to support this methodology with a low-cost set of tools that also makes optimum use of computing resources. Personal computers are used for schematic capture and logic-level simulation, while engineering workstations are used for physical placement and routing as well as switch-level simulation, timing analysis, and fault grading. Examples of projects implemented using this tool set are given. 2 figs., 15 refs.
