Book excerpt: The aim of this book is to highlight the benefits of a higher interoperability between Technology Computer-Aided Design and Electronic Design Automation, focusing on specifically selected open source tools for compact modeling. Due to the tremendous developments in semiconductor technology in recent years, device level modelling and integrated circuit design have become intimately related. However, they have been traditionally disconnected up to the circuit level. This book consists of a set of extended user manuals guiding the reader from the usual software, from multidimensional numerical process and device simulations, through compact model development and its Verilog-A standardization to carefully selected IC designs for analog, radio frequency and digital applications. Bringing together contributions from academic and industrial researchers and engineers, the book forms a valuable reference for students and those working in the field.
