Description / Abstract:
There are several aspects of an electronic design that must be captured and expressed by a design interchange format. One of these aspects is the connectivity of the circuit. The circuit connectivity or topology may be defined in several ways: as part of a schematic design, as an extraction from some layout description, or as a circuit description in some language such as the input language for a simulator. Connections need to be described between components 'in various views of the circuit. EDIF, thus, allows descriptions of circuit connections to be made in several views, most notably the mask layout, PCB layout, symbolic, schematic, and netlist views. The netlist view is designed primarily to describe the circuit connections; the layout and schematic views also describe other aspects of the circuit. The way in which the connectivity of a circuit is described is common to all such views.
