Abstract:

Details are given of the principles of a computer program which forms trial geometrical layouts of thin-film microcircuits. The designer specifies the network after having rearranged the circuit diagram to a suitable form in which the positions of the crossovers are defined. The program does not solve the fundamental topological problems which arise in arranging the layout. Given the parameters of the specific technology and the redrawn circuit diagram as data, the program forms a trial layout which is unconstrained in size. Brief comments are included about the current development of a second program which condenses this trial layout. These programs belong to a set which should enable thin-film microcircuits to be laid out with a minimum of human intervention. Author
