Cadence Enhanced Unified Custom Analog Flow

Cadence Design Systems has enhanced their Virtuoso-based custom/analog flow. The expanded custom/analog flow helps designers manage design parasitics, a DFM capability integrated within the Virtuoso environment, and the integrated Virtuoso Power System. The new features increase productivity across the entire flow from initial design specification to final GDSII and for process nodes down to 20 nanometers. The custom analog flow includes Virtuoso Schematic Editor, Virtuoso Analog Design Environment, Virtuoso Multi-Mode Simulation technologies, Virtuoso Layout Suite, Virtuoso Power System, and Virtuoso DFM.

Unified Custom Analog Flow Enhancements

  • In-design DFM capabilities integrated within the Virtuoso environment
  • Automatically locate and fix potential DFM violations concurrently during the design process
  • New Cadence Virtuoso Power System for managing power and signal integrity issues in-design
  • Parasitic-aware design features provide early exploration of implementation effects
  • Critical new editing, estimation, and automation features
  • Improved layout productivity, enhanced data-sharing around the globe, and seamless technology integration
  • New waveform viewer tuned for handling large transient simulation databases
  • Eliminates the need for design teams to buy and integrate a similar third-party tool
  • Automated constraint checking
  • New design-rule editing engine designed to handle the complexity of advanced node rule sets
  • Interactive short locator that guides the designer through a find-and-fix process for difficult layout-versus-schematic errors
  • New distributed SPICE capabilities for realizing design intent from specification within the Virtuoso Analog Design Environment to foundry-qualified SPICE models
  • Built-in publishing and design checking software facilitates maintaining design intent in a globalized work force
  • Support of the Common Power Format ensures design intent is maintained across analog/digital domains
  • Analysis of pre-extraction parasitics helps model the potentially detrimental parasitic effects and guards against them
  • Simultaneous top down and bottom up full-custom floorplanning enabling advanced high altitude visualization and increasing custom layout productivity
  • Use of fully integrated VerilogA, VerilogAMS and Wreal models for mixed-signal simulation enabling higher performance at all levels of validation
  • Uses signoff-proven engines within the Virtuoso environment, enabling correct-by-construction design methodology that eliminates lengthy signoff iterations
  • New automation to enable automated and concurrent find-and-fix methodologies for LVS, DRC, and DFM optimization in-design
