In the progress of product researching and developing, it is very necessary that the founding of virtual prototype. In the phase of circuit simulation, there is a big problem in system simulation, which is the absence of SPICE model of mixed- signal. While solving the problem, the self-making device model is very powerful to finish the 'Top-down' simulation by the advantage of VHDL-AMS language. To find the advantage of the VHDL-AMS language for analog system, this modeling method is also effective to describe the mixed-signal system's structure and action.

This paper outlines a framework which supports the use of multiple perspectives in system development, and provides a means for developing and applying systems design methods. The framework uses "viewpoints" to partition the system specification, the development method and the formal representations used to express the system specifications. This VOSE (viewpoint-oriented systems engineering) framework can be used to support the design of heterogeneous and composite systems. We illustrate the use of the framework with a small example drawn from composite system development and give an account of prototype automated tools based on the framework.
