SAN JOSE — Printed circuit board and multichip module design software sales dipped 5.4% in the third quarter, bucking an overall rise in demand for electronic design automation tools.

SANTA CLARA, CA – Bogatin Enterprises next month will teach three one-day classes on design techniques for differential pairs, vias and S-parameters.

On Feb. 3, S-Parameters for SI Applications will take place here, and will cover S-parameters and how to data mine valuable information contained in 72 unique elements.

On Feb. 4, Differential Pair Design will cover the four families of SI problems: losses, reflections, noise and mode conversion, and how to minimize these problems and design high-speed channels.

On Feb. 25, Transparent Via Design will cover design techniques to make discontinuities nearly transparent and analysis of techniques to evaluate their real impact.
