Silvaco’s SmartSpice is a high performance parallel SPICE simulator that delivers industry leading accuracy. It is a proven, comprehensive solution for applications including simulation of complex high precision analog and mixed-signal circuits, memory, custom digital design and characterizing cell libraries of advanced semiconductor processes. It uses an intelligent architecture deploying multiple solvers, stepping algorithms and computation techniques. The result is accurate, robust convergence and industry leading performance and capacity – over 8 million active devices. It is compatible with HSPICE® and Spectre® for netlists, models, analysis features, and results – plus large libraries of calibrated device models are available. Featuring integration with Silvaco Gateway schematic editor and SmartView waveform viewer, SmartSpice fits seamlessly into front-end analog IC design flows.

SmartSpice supports advanced features:

  • Real-time waveform analysis update through interactive rubberband feature for on-the-fly circuit tuning.
  • Complete suite of built-in local and global circuit optimization engines
  • Rad-hard simulation capability for modeling and analyzing radiation effects due to single event effects (SEE), and dose rate (DR)
  • Verilog-A language support provides circuit designers and model developers with an easy-to-use, comprehensive environment for the development of circuit macro-models, new compact device models, and the use of  existing industry standard compact models in SmartSpice simulations.

SmartView is Silvaco’s graphical environment for performing real-time and post-simulation waveform viewing and data analysis of analog, RF, digital and mixed-signal circuits. User configurable preference controls, an intuitive GUI and a library of advanced measurement makes SmartView an easy to use and productive simulation analysis environment. It support real-time interaction with SmartSpice and Gateway schematic editor for on-the-fly design tuning.

SmartSpice Pro delivers superior performance for SRAM and TFT-based display designs. Unique fast-SPICE algorithms are combined in the tool to provide fast and SPICE-accurate simulation for multi-million-size memory and display circuits.
