A Computer-Aided Design System for Hybrid Circuits

A software system used to aid hybrid circuit design, layout, and documentation is described. The intent of the programs is to address the design needs of a company that requires a considerable number of new custom hybrids each year. The system, called HCAD, resides on a mainframe engineering computer and is available to designers on a time-share basis via interactive graphics terminals. The system acts as a design aid for the user by handling difficult computations and by storing large amounts of data while leaving most of the creative tasks to the user.
