Reinforcing the Connection Between Analog Design and EDA (invited Paper)

Building upon recent advances in analog electronic design automation (EDA), this paper discusses directions for reinforcing the connection between design and EDA, in order to develop solutions that are meaningful to designers. Two aspects, both related to bridging the gap between EDA and designers, are highlighted. The first discusses the use of test structures to generate meaningful characterized data to aid design automation, specifically understanding the impact of random, correlated, and systematic variations on the design of matched structures. Results on a recent test chip that analyzes these variations and their impact on EDA design choices will be presented. The second illustrates a design testcase that applies analog EDA techniques, using the ALIGN layout engine, to design an RF MIMO receiver, and describes how this experience has helped both in advancing the state of analog EDA and in building circuits with enhanced designer productivity.
