An expert system to aid in CCD design: XAS

XAS is an expert system that contains knowledge for designing and simulating CCD chips. It synthesizes correct simulation programs automatically given the same process and mask data used by chip designers and selecting parameters according to the purpose of the simulation. XAS has the following characteristics. The XAS editors have expert knowledge of CCD chips and use it to display appropriate figures and menus. Because the user interface is mouse based, inputting data is both interactive and easy. In addition, XAS gives the same environment on every workstation connected within a local area network, so that many designers can access the system simultaneously.<>
