Application of Virtuoso iQuantus Insight and Quantus Insight Flow on FINFET advance processes to accelerate post-simulation iteration

Abstract： With the evolution of process, the continuous scaling of size introduced more parasitic paths and larger parasitic resistors, causing great differences between the results of post-simulaion and pre-simulation. How to quickly narrow the gap between post-simulation results and pre-simulation results becomes an improtant topic. In traditional design, parasite can only be analyzed through tools like Quantus Extracted View, and the results cannot be displayed in more detail. How to better analyze the parasitic netlist has become a great challange. In addition, after problems found in post-simulation, the design can only be optimized by an iteration process of modifying the circuit design-modifying the layout design-redo the post-simulation. This iteration process is a long period, how to reduce the iteration time cost becomes a key issue for design companies. Virtuoso iQuantus Insight (ViQI)/Quantus Insight (QI) can do accurate parasitic analysis and visuallization based on the parasitic netlist file. Engineers can use this to accurately analyze parasitic parameters, and assume the parasitic values to optimize the design without layout modification. This article describes how to fast iterate the circuit design using ViQI/QI, and so greatly improve work efficiency.
