PRIMS is an interactive system to be used in the layout of hybrid circuits. The layout involves positioning integrated circuit chips and resistors on a substrate surface. Conducting paths are then defined in order to make interconnections between chips, external connection pads positioned around the edge of the substrate, etc.PRIMS is actually a language which includes commands for defining regions corresponding to integrated circuit chips, and for causing the system to define a tree of conducting paths to interconnect a set of points. There are also commands for displaying a partial layout, for editing the layout, and for generating plotter code for the final layout.
