Why More than 50,000 Copies of Intusoft's ICAP/4 Being Used

Intusoft continues to demonstrate time-tested leadership in analog, mixed-signal and mixed-systems design automation. Its 20+ year track record is steadfast, making Intusoft today's leading SPICE-based EDA provider, notably for its tool power, personalized customer service, ease of use and outreach to the engineering community.

With today's conservative economic times and the blistering pace from design to production, it's imperative that companies employ powerful, yet easy-to-use tools that are cost effective. Intusoft is dedicated to providing the industry's best tools for design entry, simulation, verification and test development. The company has devoted several man-years in advancing its IsSpice4 simulation technology, and supplying the industry's most exclusive software for board level and IC design. But product commitment is only the beginning. Intusoft's customer support, technology partners, customer marketing, responsive technical support and centralized operation are unparalleled, stengthening the commitment to its customer base and the EDA industry.

Intusoft - Still Today's Premiere SPICE Tool Provider in Many Ways

Intusoft's team of technology professionals has achieved several noteworthy milestones. In addition to providing the best price-to-performance ratio of products, and unparalleled service to customers, other noteworthy aspects of the product line include a track record of industry firsts.

• ICAP/4 provides today's most abundant set of analog and mixed-signal product features, with scalable offerings that conserve price, yet provide top performance.
  
  
• Complete assistance is provided for all levels of tool users, including a first-time user's tutorial with corresponding movie, comprehensive "Getting Started" and "IsSpice4 Users" guides, in-application movies and extensive in-application help.
  
  
• "SpiceNet" is a powerful design entry and management schematic system that features a patented layering capability. Layering provides instant highlighting of different schematic sections from the top level (e.g., power layer, pre-amp layer, signal processing layer, etc.), fast wiring between layers, and easy formation of different schematic configurations for design, debug, production, regression testing and reuse.
  
  
• IsSpice4 (4th-generation SPICE technology) features enumerable enhancements and extensions to SPICE3 (combined with XSPICE), including extensive refinement of DC and transient convergence algorithms, and algorithms for optimizing simulation speed and accuracy. IsSpice4 is ideal for signal processing, RF, power electronic and IC/ASIC design.

  - DC, AC and industry's only transient sensitivity analysis, which also monitors a gamut of electrical measurements (i.e., rms, pk-pk, standard deviation, rise time)

  - Industry's most extensive convergence enhancements: Automatic Gmin stepping/Source stepping algorithms; pseudo-transient algorithm; improved predictor-corrector, latency and bypass algorithms; improved program defaults; full gear integration option; matrix load bypass algorithm; enhanced sparse matrix algorithm; alternate UIC; new VSECTOL and ICSTEP convergence algorithms; enhanced RELTOL and AUTOTOL convergence options; convergence wizard; and access to full simulation parameters

  - All active components support distortion analysis

  - Individual device temperatures can be set to a different value than the overall circuit temperature, allowing simulation of a "hot" component. Parametric sweeps can be run for virtually any parameter.

  - Unique interactive simulation accommodates on-the-fly component changes; simply set a button for continuous change, or alter a component as an equation or function of another component change, all without schematic intervention. This includes real time waveform views during simulation. Single and nested sweeps are also provided. IsSpice4's interactive capability also enables user to set simulation breakpoint conditions during runs, i.e., voltage or current level is reached, or a device parameter meets an assigned condition such as device breakdown, safe operating area or time-dependent event. Pause/resume simulation is also provided.

  - IsSpice4 supports pole-zero and 2-port analyses, plus Smith charts.

• Industry's first Interactive Command Language (ICL) enables flexibility in advanced analyses such as Monte Carlo statistical, worst case, extreme value, root summed squares, optimization and transient sensitivity. ICL enables users to select these analyses as is, or optionally modify them for different performance. All these can be used in conjunction with AC, DC, transient and operating point analyses.
  
  
• Industry's most powerful waveform processor (IntuScope) includes unique capabilities such as three options for instantly updating "previously viewed" waveforms, more than 125 waveform processing (calculator) functions, and ICL scripting for modifying existing waveform calculator functions or creating new ones. Waveforms can also be instantly displayed on the schematic. IsSpice4 also simultaneously displays progressive waveforms for different types of simulation runs.
  
  
• Industry's only automatic user-defined measurements and stress alarms enable prescription of electrical test measurements throughout design nodes and/or components, including corresponding pass/fail test limits. Electrical values are charted numerically, while pass/fail indicators display out-of-tolerance measurements.
  
  
• Advanced modeling includes many industry firsts such as the very latest BSIM4 model; hysteretic average models; expressions such as for frequency dependency for R, L and C; SMPS schematic templates, General Feedback Theorem models for measuring open loop response without breaking a loop; and non-linear magnetic, power, RF, IBIS, AHDL, and "array hardware interface" models. Device libraries exceed 24,000 simulation models.
  
  
• Several SPICE modeling tools include datasheet entry and an optional C-code development kit, plus free modeling service.
  
  
• Industry's only automated fault and test synthesis programs ensure high production yield, including pseudo test code generation for automated test equipment and field devices.
  
  
• Industry's only full magnetic design and synthesis software option is available for ICAP/4.
