Abstract

In the design and development of a computer there are many areas of repetitive analysis, and there is much recording, changing, and checking of detail to be done. It is necessary for this detail information to be absolutely accurate; therefore, this system utilizes computers such as the IBM 704 or 705 in the layout and implementation of logic, maintaining a record of such logic including engineering changes, print on a printer the logic pages or circuits, check the logical design for conformance with design rules and prepare the wiring lists, bills of material and the other outputs desired.

Design Automation System

In the design and development of a computer there are many areas of repetitive analysis, and there is much recording, changing, and checking of detail to be done. It is necessary for this detail information to be absolutely accurate; therefore, this system utilizes computers such as the IBM 704 or 705 in the layout and implementation of logic, maintaining a record of such logic including engineering changes, print on a printer the logic pages or circuits, check the logical design for conformance with design rules and prepare the wiring lists, bills of material and the other outputs desired.

The system comprises the storing of large amounts of data regarding the electronic design of a machine system on magnetic tape which can be processed in a computer to add, replace, sort, collate, check and extract information necessary for the preparation of the various engineering documents. The principal advantage lies in the reduction of the repetitive processes necessary for such work by a design engineer.

From the chart it will be seen that the engineer enters the raw logic into a listing which takes care of the logical implementation and physical placement of the circuits. The output is a tape containing a record of the actual circuits necessary to perform a given logic with their physical locations specified. At this point, logic minimization and powering can also be added. The data then goes to the logic page assignment where the logic is assig...
