Abstract
A computer model for facilitating computer assisted design includes data structures which are flexibly organized by storing of information in accordance with entities or simulations thereof (including symbolic layer entities, area entities, area spec entities and area spec usage pattern entities), which are hierarchically associated both by relationships between them at a given level of abstraction of the physical entity they represent and by various attributes that correspond to different levels of abstraction in graphs. The graphs are freely mappable onto any desired fixed data structure such as a hierarchical area tree. Each hierarchical level and particularly the symbolic layer entity within the computer model provides data hiding at each lower level thereof and thus provides data hiding in the fixed data structure by virtue of the mapping function in order to reduce data processing overhead for manipulation of the fixed data structure. Further spatial restriction within one or more symbolic layers is provided by means of an applications window entity. Data compaction is provided by provision of data sharing of area spec entities by plural area entities which are otherwise uniquely maintained.
