Automated cable schematic generation

Abstract

Input data is partitioned and organized by building a sequence of predefined data structures corresponding to respective data models, each having a different organization and including pointers for propagating input data or data from a preceding data structure therethrough. Each data structure also includes fields for data values which may be input by a user or computed from other data stored therein and pointers referencing instances in a previous data structure in the sequence of data structures. As applied to the production of schematic drawings of cables connecting portions of a large and complex system with a high uniformity of style, such as to ANSI standards, the data is organized by unit, connector and pin priority and in prioritized groups of nets or subnets and partitioned into sheets for rendering in a standardized format. The pointers to instances of data in previous data structures facilitates collection of data for the production of other types of drawings at differing degrees of abstraction, producing reports referenced to drawing content and the like.
