Abstract

The design of the CLEO-III Trigger produced 24 different multilayer printed circuit board designs, and over 100 FPGA configurations. Only one board design was intentionally prototyped and respun; only one board design was respun due to design/layout error; only one board design had more than 6 ECO wires. A detailed case study of the CLEO-III Trigger design methodology is presented. Scheduling, budgeting, manpower allocation, and architectural refinements are reviewed. In each area, comparisons are provided between the original projected needs and the actual final consumption. These quantitative data are offered as a sample reference for use in project planning and estimation
