DescriptionElectromigration is emerging as a bigger challenge in analog layouts in advanced nodes than ever before. Analyzing designs to ensure interconnect capability for high currents and low resistance paths becomes an overhead in the design cycle, when violations are checked and fixed in the end. The latest offering by Cadence Virtuoso in this direction is SDR (Simulation-Driven Routing). It is an advanced methodology that assists designers to create routing that is correct-by-construction for electromigration and IR drop constraints. In this work, SDR has been deployed on an analog block for interconnecting devices at 28nm node. It was observed that through SDR, EM-compliant routing was implemented in 30% less time, as compared to the traditional way, with almost 70% accuracy for most of the signals. The overall 40% increase in productivity appears impressive to obtain a layout that meets all electrical constraints with sign-off design reliability.
