Abstract
This chapter explores the suitability of unified modeling language (UML) techniques for defining hierarchical relationships in analogue and mixed signal (AMS) circuit blocks, and extensible markup language (XML) for storing soft AMS intellectual property (IP) design rules and firm AMS IP design data. Both aspects are essential to raising the abstraction level in synthesis of this class of block in SoCs. The various facets of AMS IP are discussed, and explicit mappings to concepts in UML are demonstrated. Then, through a simple example block, these concepts are applied and the successful modification of an existing analogue synthesis tool to incorporate these ideas is proven. The central data format of this tool is XML, and several examples are given showing how this metalanguage can be used in both AMS soft-IP creation and firm-IP synthesis.
