Intusoft Releases (8.x.11 v. 2817) SPICE Simulation Tool Suite

Long Beach, CA (October 24, 2006) -- Intusoft announced today the release of its ICAP/4 8.x.11 Build 2817 SPICE-simulation tool suite for analog, mixed-signal and mixed-system design. The announcement was made at the Power Electronics Technology Convention in Long Beach, CA. A host of enhancements have been added to the 11th-generation software from its former Build 2641, and are being showcased at booth # 641. The "x" in 8.x.11 deciphers Intusoft's low priced solutions, through high-end ICAP/4 Professional and Test Designer products.

Software Enhancements Driven by Reference Accounts:

Tim Ghazaleh, director of marketing for Intusoft, commented that the company's reference accounts again brought forth a number of desired features for the software this year. Several product enhancements were installed across the "SpiceNet" design entry system, "IsSpice4" simulation output file, automated electrical measurements readout, and waveform viewing. Further, a unique Digital Data Viewer was added to ICAP/4's "IntuScope" waveform viewing and signal processing tool, designed to eliminate the cumbersome task of deciphering bus input signals with output values.

New Digital Data Viewer:

ICAP/4's Digital Data Viewer (DDV) is an innovation that charts data resulting from simulation of digital buses (e.g., bus feeding a 7-segment LED IC). The process requires initial set up of a data template that defines buses and their parameters, such as input data patterns at targeted schematic nodes, which are prescribed as binary or binary-coded decimal. Corresponding outputs are defined in decimal, hexadecimal, octal, binary, or mnemonic format. The output of a single analog node can be included as an analog value. The user also specifies what signal to synchronize the bus data to, such as either edge of a system clock. Bus high and low logic levels are computed by the simulator, or can be specified by the user. After simulation, the user can move IntuScope's waveform cursor along the clock signal, as corresponding text lines of bus data in the table are highlighted in DDV's viewer window. Also, any data line in the table can be selected, and IntuScope's cursor will jump to the corresponding clock transition time.

New ICAP/4 Features:

8.x.11 Build 2817 has enhanced SpiceNet's display of DC operating points, component properties, user-specified custom part bins, and waveform graphs displayed on the schematic. Following a simulation run, the display of automatically charted electrical measurements has also been enhanced. Management functions for Monte Carlo statistical analysis now run much faster. With component sweeps, multiple components can be assigned the same sweep variable and swept as a group through a prescribed range of values. Many designers are interested in key data collected from a SPICE simulation output file, so ICAP/4 has added operability enhancements for the IsSpice4 simulator's output file. Other features with Build 2817 include waveform management and importing of data in IntuScope more powerful.

Industry's Largest Device Model Library:

In the modeling domain, Intusoft's free custom-modeling program, which is open to the engineering community, added 40 new simulation models to ICAP/4's previous release of 444 new devices. These are full custom models developed by the company's in-house modeling team; the requested IC and discrete models are not furnished by vendors. This brings the total simulation library size to more than 23,500 device models - the largest offering in the industry. In December of 2005, a new saturable-core SPICE model was added to thousands of cores featured in ICAP/4's "Magnetics Designer" magnetic design and synthesis option.

ICAP/4 8.x.11 Build 2817 provides a New User's Guide that enables quick success in basic design entry, schematic operations, simulation setup and execution, cross-probing the schematic for waveform views, waveform processing and calculator operations, window configuration management, component sweeping and more, in less than an hour. An extensive collection of in-application help, movies, and manuals are also part of ICAP/4 Build 2817.

Product Backgrounder:
