A System for Computer-aided Design of Printed Circuit Boards


Book Description

A general purpose system for interactive computer-aided design of printed circuit boards is described. Included boards is described. Included are details for encoding a circuit diagram in the computer, the placement of electronic component packages, the determination of a link/wire list and the routing of this list to obtain a wire layout. Design documentation in the form of component schedules and layout drawings are produced so that artwork can be generated on a Gerber drafting machine. A feature of the system is the method by which the routers find different size wire-paths on successive grids of increasing resolution. The use of this method approximately halves the routing time and increases the link connection rate by over 15%.

A Computer Aided Design Methodology for Printed Circuit Boards


Book Description

We present a design methodology for realizing VLSI printed circuit board (PCB) designs using Computer Aided Design (CAD) tools on powerful workstations. The workstation and CAD tools allow one to create a gate-level design using TTL parts and interconnecting wires, simulate the functionality and timing of the gate-level design using TTL parts and interconnecting wires, simulate the functionality and timing of the gate-level design, package the designs TTL parts into PCB parts, place and route the PCB, create manufacturing data, and simulate the design at the board-level. A design example, the VLSI-PLM PC Board being developed at the University of California at Berkeley, is given to illustrate this procedure. The VLSI-PLM PC Board is a processor board for the VLSI-PLM Chip [SRINI], which is a high performance CMOS processor for executing computer programs written in the Prolog language.
