Premiere Analog & Mixed-Signal Solution Made Easy

If the industry's highest-performing and most affordable analog, mixed-signal, mixed-systems and IC simulation solution is on your list of tool requirements, then ICAP/4 Professional is your choice. This full-featured offering is at the apex of today's most comprehensive simulation solutions. It not only furnishes time-tested technology and unprecedented capability geared for simple design to highly complex architectures, but it also supplies an intuitive approach for fast design, debug, verification and production test.

Power is shown in several unique ways with ICAP/4 Professional. For instance, ICAP/4's patented design entry system (SpiceNet) features different schematic layers (overlays) that easily combine to create different design configurations for debug, test, reuse, PCB and production - all stored in a single database. Layers are often used to construct different design sections, all quickly wired together and highlighted for fast visibility from the composite design. Also, any change in a design configuration is propagated to all others. SpiceNet also includes footprint information for operation with the Bartels AutoEngineer PCB layout and route software.

Another powerful feature of ICAP/4 Professional is "Design Validator," which provides a convenient way to easily run multiple types of simulation runs; chart electrical measurements and out of limit conditions and detect faults. Measurements include things like peak voltage, average current, rise time, power, temperature and supply voltage drop. Prescribed fault conditions, such as R1 open and Vbe short, are automatically injected and simulated for pass/fail signal compliance throughout the design. Design Validator includes aids to help interpret results such as histogram bars, colored alarms and numerical data all conveniently charted.

Of course ICAP/4 Professional features the industry's legendary "IsSpice4" analog and mixed-signal simulation kernel, including countless enhancements for optimum DC convergence, speed and handling of tough designs. IsSpice4 is even used as the simulation engine with Intusoft's major partnering companies.

ICAP/4 Professional's debugging tools help any engineer caught short of time to meet production in the fastest way possible. Pressing a button to sweep component values (as values, equations or functions of other components' variation) and view real-time signals, mimics actual lab debugging but with much more versatility. Fast nested sweeping of multiple components, plus updating previously viewed waveforms in three selectable modes are other time savers and helpful during debug. For design verification, several advanced analyses promote ultimate design reliability and manufacturability, reaching far beyond traditional capability of lab equipment and breadboarding. ICAP/4 Professional includes Monte Carlo analysis for analyzing circuit variations created by statistical variation of component tolerance values as found in production. Worst Case and Extreme Value analyses bring components to their most adverse behavior during simulation runs. Root Summed Squares analysis similarly imposes worst-case variation for certain types of non-linear design.

Other valuable features include the "DSP Designer" option, which enables digital control and other aspects of DSP design to be visually simulated as transfer functions and equivalent assembly code instructions using special device models. Corresponding waveforms include Bode plots of hidden parameters within Z-transformations. Real-time code generators also drive the DSP board in DC, transient and AC domains via a serial interface, and retrieve waveforms viewable alongside simulated waveforms through an IntuScope plug-in, . The product is also valuable for verifying DSP assembly language, though this tidius process is automated with IsSpice4 and DSP Designer's Integrated Development System loaded onto the PC.
