Abstract: This report describes a layout synthesis system called AISCE. The system accepts structural or logic hardware design specification and creates physical layout of integrated circuit automatically. AISCE contains several parts: schematic capture system, netlist compiler, module generators for data and control path, tools for floorplanning, placement and routing, simulators and verifiers, etc.. They are all integrated into one design framework. Following AISCE’s synthesis flow, this paper introduces each part of the system. Experimental results show that AISCE is an efficient and promising system.
