Full Functionality

  • Easy to create symbols, subcircuits, subschematics, and Verilog-A models
  • Comprehensive symbol creation and editing features for simulation, schematic-driven-layout, and LVS compatibility
  • User-configurable keys for repetitive tasks and to emulate legacy capture tools
  • Comprehensive search and replace to process porting, IP reuse, and interactive design
  • Hierarchical capture for modular, reusable designs, libraries, and working with legacy circuits
  • Powerful edit-in place functions with wires, busses, bus ripping, and bus merging
  • Designer configurable rule checks show electrical drawing rule violations and illegal names


Gateway200 provides a front-end to hierarchical design with cross-probing, marching waveforms, analysis options, and optimization.


Ease of Use and Adoption

  • Easy to use for both new and experienced designers with intuitive left-to-right design approach, tool tips, and batch simulation control
  • Easy to set up multi-user environment with libraries and import legacy data using EDIF
  • Help functions and tool tips for new users
  • Parameter minimum/maximum checking eliminates entry errors
  • Supports wire to wire, wire to pin, wire by name, and implicit/global connections


Integrated Custom IC Design Platform

  • Front-to-back design automation solution for custom analog circuits
  • Connects Silvaco behavioral modeling, schematic, circuit simulation layout, LVS, and parasitic extraction with proven feedback flows
  • Integrated with SmartView Graphical Waveform Postprocessor for overlayed measurements of delays, slopes, overshoots, rise-time, and eye diagrams – complete with vector calculator
  • Powerful cross-probing between schematic and post-processing provide real-time design feed back
  • Call-backs evaluate expressions in real-time for design rules, tolerances, parametric calculation, and process skews
  • DC bias display for currents and voltages throughout hierarchy


Gateway200 provides an environment for mixing transistor and behavioral level (Verilog-A) schematics to minimize design time and maximize efficiency. Verilog-A schematics may be used for behavioral block design or compact model design.


Designer Productivity

  • Creates multiple views for layout, simulation, and LVS for design integrity and smooth tapeouts
  • Spreadsheet data entry, netlist import, EDIF reader, and automatic symbol generation for easy re-use of legacy circuits
  • Supports encrypted netlists behind symbols in design kits for IP distribution
  • Marching waveforms allow real-time viewing of simulation results to check on long simulations
  • Efficient control of the design flow between schematic, simulation, and analysis
  • Highlights errors and zooms to schematic location/level for correction


DC bias for currents and voltages for Hierarchical and flat drawings.
