User interface management system (UIMS) is one kind of software development tool. According to the characteristic of the user interface of VLSI/CAD software, we design and implement a UIMS-GI, which supports graphical interaction. It is based on the simplified event-respond model and its main aim is easy used. It produces the user interfaces of the application programs according to the user s interface descriptions. GI supports menu, keyboard and window input and serves the application programs in the parallel mode,so it not only has good interactive characteristic,but also also the entirety and indepence of the application programs.
