Your Prescription for Reduced Complexity

ICAP/4Rx is a fully integrated, mixed-signal design simulation system that includes everything you need to reliably complete all types of board, engineering system and IC-level design. Whether you are looking to upgrade your evaluation version of ICAP/4, or getting started with a robust SPICE offering, ICAP/4Rx strikes a perfect balance between ease-of-use, full power and very low price. It has the capacity to handle tough designs, yet removes the learning curve associated with using extensive SPICE analyses. With today's demanding analog and mixed-signal design, simulation power, ease of use and affordability lie at the apex of tool requirements, as provided by ICAP/4Rx.

ICAP/4Rx includes "SpiceNet," Intusoft's 5th-generation design entry tool. SpiceNet provides a patented layering and configuration system that enables the creation of different schematic layers (example: power supply, signal processing section, amplification circuitry and final output stage), quick wiring between layers, and "highlighted" visibility of all layers from the composite design. Schematic layers can be saved to create different design configurations for debugging initial design functionality, regression testing, production, military standard, PCB layout, etc. Design changes invoked in one configuration are automatically propagated to all other versions, saving time and optimizing design management. SpiceNet even displays operating point data, waveforms, and user-created artwork and text directly on the schematic at the click of the mouse.

Of course, ICAP/4Rx includes Intusoft's time-tested "IsSpice4" analog and mixed-signal simulation kernel, featuring more enhancement than any SPICE kernel on the market for convergence, accuracy, speed and interactive capability. It also includes component and temperature sweeping for quickly generating curve families for powerful what-if analysis. It even has pole/zero analysis for improving design stability.

The "IntuScope" waveform viewer and post processor features 150 waveform calculator and signal processing operations, all scripted for optional modification by the user. It also features unique features such as three modes of updating previously viewed signals during repetitive debug runs, plotting of any variable verses another (e.g., gain vs. temperature), and view of multiple simulation run types at the click of the mouse.

ICAP/4Rx contains a surprising amount of ready-to-use simulation models, totaling 15,000+ parts of a wide variety. Analog, digital and a variety of special devices are included in the collection. These work with the industry's legendary IsSpice4 simulation engine, which contains enhanced algorithms for superior design convergence, simulation accuracy and speed simply not found in competitive offerings.

But this is only the start of a long list of benefits found in ICAP/4Rx. See if the features listed below clearly make this offering the best choice for your design needs.
