Commercial CAD software now integrates the various stages of microwave circuit design: schematic capture, simulation and layout. This paper reviews the different CAD packages that are available for microwave circuit design. The basic principles employed in the modelling of microstrip circuits are introduced and the reasons for the extensive use of frequency-domain simulations are explored. The developments in nonlinear, electromagnetic and system-level simulation methods are described. %K Teoría de la Señal y las Comunicaciones %K Circuitos CAD %K Diseño de circuitos CAD %K Simulación digital %K Análisis de la frecuencia de dominio %K Circuitos de micro franja %K Circuitos de microondas %K Circuit CAD %K Circuit layout CAD %K Digital simulation %K Frequency domain analysis %K Microstrip circuits %K Microwave circuits %K Computer Aided Design (CAD) %K Diseño asistido por ordenador %~ GOEDOC, SUB GOETTINGEN
