XML Specification for Complex Digital Logic Components

Considering that the digital system design is a complex task, in order to meet some requirements such as effective performance, low costs and high reliability, and improve the development quality and efficiency, design activities need to be carried out under a precise description for completing the design cycle. This paper presents the XML specification method, and defines a subset of XML syntax for the complex digital logic component model. In this method, the logic mapping table is used to describe combinational logic components, state-oriented finite state machine to describe the behavior models of sequential logic components, and structure-oriented connector to describe structure models of composite hardware components.
