Template-Driven Parasitic-Aware Optimization of Analog Integrated Circuit Layouts*

Layout parasitics have great impact on analog circuit performance. This paper presents an algorithm for explicit parasitic control during layout retargeting of analog integrated circuits. In order to ensure desired circuit performance, bounds on layout parasitics ’ magnitudes are determined first. Then, graph techniques are coupled with mathematical programming to constrain layout geometry based on these parasitic bounds. The algorithm has been demonstrated to ensure desired circuit performance during technology migration and performance specification changes
