Abstract : As a part of this research, a content addressable memory(CAM) controller chip has been recently designed to control the operation of the CAM chips. There is also the need to design, implement, and fabricate a general purpose Printed Circuit Board (PCB) to implement specific application circuitry at a system level. For the Content Addressable Memory system this consists of the CAM chips, the CAM controller, and interface circuitry to test the CAM chips in real environments. This thesis investigates the design of an AFIT VME design board. This effort concentrated on implementing a prototype general purpose printed circuit board for SUN/3 Workstation. This thesis presents detailed design of the functional blocks like VME interface, testing electronics, and input/output interface. The board size is 14.5 X 15.125 -in. and about half of the board is left unused for user application. The user can implement application specific circuitry in the provided space for testing in a real time environments. An eight layer printed circuit board has been laid out and routed using DASH-PCB design system. The final product will be a valuable tool for testing VLSI chips and other applications in a real time environments.
