1. A system for generating integrated circuit mask artwork from a schematic of an electrical circuit, said electrical circuit containing electrical components and connections between said components, said system comprising:

  • artwork library database containing macros, each of which generate artwork for one of said electrical components of a particular technology type, wherein said components are identified by a component designator;

    device generator means for defining the type of circuit to be executed and for executing the macro for that circuit independent of the component'"'"'s particular technology type;

    means for defining relationships between said circuits, said relationships specifying desirable physical relationships between sets of related circuit components which influence their performance;

    means for determining placement of said components on said artwork including means for determining placement groups, the groups consisting of groups of components with related placements based on said defined physical relationships;

    means for arranging said components so as to optimize a predetermined parameter, the parameter being a function of the physical relationship between the components;

    means for eliminating overlaps between said components by moving said groups as a whole wherein said defined relationships are preserved; and

    means for routing the electrical connections between said placed components.
