A Training Tool for MMIC Designers

Abstract

A framework program MADE (MMIC Automated Design Environment) (figure 1) is presented which is used in the training of undergraduate and postgraduate engineering students for the design and layout of MMIC circuits. The expert system submodules of MADE; ADAM, GALEDA and GALA are' described. Starting from a performance specification, the user is advised' on microwave circuit topology selection, design of custom and standard cells including foundry -specific parasitics and optimum layout to minimise real estate usage and avoid Intercomponent coupling. CIRCUIT DESiQNUndergraduate and postgraduate students at Queens University are familiar with microwave design concepts. They do not, however, appreciate the advantage offered by modern microwave CAD tools in design. A student will usually be presented with a circuit specification such as a broad band amplifier for example. lnstead of producing a
