Data integration refers to the ability of applications to share data and the ease with which this data is shared. Data integration is one of the fundamental missing pieces of functionality in ECAD systems created with tools from multiple tool vendors. Current systems meet neither the user's nor the tool supplier's needs for sharing data.A data integration solution is composed of five parts: semantics, syntax, storage, translation, and mechanism. There are only a handful of data objects transferred among ECAD applications. The key to obtaining data integration is to develop a data model that is common to all applications for each of these objects.The goals for a data integration architecture are: use one data model, meet tool performance and resource requirements, provide an extensible model and format, accommodate tools from any supplier, provide a single data interface, and permit portability.An ECAD data integration architecture to meet these goals consists of: a system context data model, a data model for each system data object, one format and access method for each object (the canonical form), and a data controller to control access to and translation of the data objects.An initial implementation of this architecture might consist of a system context data model and data models and canonical forms for schematic capture symbols and simulation netlists. In the short term a very simple integration mechanism is acceptable; in the long term an object management facility holds the most promise as a flexible and general integration mechanism.
