The Menu Driven Chip Layout Language MDLL is a microcomputer-based design tool used for representing the physical layout of integrated circuit designs in the Caltech Intermediate Form CIF. MDCLL is based on the Chip Layout Language CLL created by Tim Saxe of Stanford University and as modified at the Air Force Institute of Technology. MDCLL leads the user through interactive menu-driven functions, allowing the user to represent a circuit design in CIF however, the user sees a language similar to CLL even though the file is stored on disk as CIF. The output CIF file is suitable for use with other Computer Aided Design tools or for use in the fabrication process. MDCLL uses a cell-oriented design methodology in which the user defines cell, and then the user combines these cells with the necessary interconnects to form the layout of an entire integrated circuit. Cell interconnections are possible by placing wires, abutting cells, or by overlapping cells. The main functions of MDCLL are to create a new cell, delete a cell, place a cell, move a cell, modify a cell, interconnect cells, and print the CIF file of a cell. Theses
