ABSTRACT
CIBOL (CIrcuit BOard Layout) is an application program that uses a computer graphics facility to aid in the design of low density discrete component printed wiring boards. There are three distinct program phases: creating the board outline, positioning the components, and routing the interconnections. A light pen and scope display are used interactively during the three program phases. The program directly generates manufacturing information on auxiliary peripherals in the form of parts lists, component layouts, drilling lists and artmasters. The use of the program has resulted in considerable savings in the cost of producing printed wiring board designs and reduction in the turnaround time from design inception to completion.

An interactive layout system of analog printed wiring boards
DAC '79: Proceedings of the 16th Design Automation ConferenceApart from the layout of digital printed wiring boards (PWB's), no specific development has yet been reported on the layout of analog PWB's which contains not only placement and routing but also artwork to generate a variety of geometric wire patterns ...
An Approach to Gate Assignment and Module Placement for Printed Wiring Boards
High-density packaging is one of the most urgent requirements in the design of digital systems. In the assembly of such systems, printed wiring boards (PWB's) are used very often to provide the necessary interconnection among circuit modules. Thus, ...
A minicomputerized automatic layout system for two-layer printed wiring boards
DAC '77: Proceedings of the 14th Design Automation ConferenceThe requirement for high density packaging is dominant in the design of electronic systems. In the assembly of such systems multi-layer printed wiring boards are often used to provide the necessary connections among functional modules, and as the wiring ...
