DescriptionArea estimation of IC layouts has become an important requirement for early design and top-down chip planning tools. The relation of area and aspect ratio is necessary for layout planning. For custom analog IPs, matching placement and routing is very important in layout design of high-performance analog circuits. System design complexity is growing rapidly. In this paper we propose a solution based on Pulsic’s AnimatePreview. AnimatePreview gives designer quick, easy and accurate physical information about their analog circuit while they develop their schematic, so they can make better decisions earlier in their design flow and reduce iterations.
