New SPICE Simulator Has Unique Features

At Wescon/95 Intusoft will be showing the latest version of its popular
Windows based ICAP/4 simulation system. ICAP/4 is an integrated suite of
design tools consisting of schematic entry, SPICE based simulation, model
libraries and post processing. The suite offers capabilities that cost
tens of thousands of dollars on Unix platforms and inherently includes the
graphical ease of use features brought about by the Windows interface. In
this latest update to ICAP/4, the schematic entry and modeling portions
have been augmented with a number of unique features. 

The new ICAP/4 system includes thousands of new digital, analog, and
sampled-data models. Users can even "plug in" system level blocks like FIR
and IIR filters, complex state machines and mathematical transfer
functions and simulate them along with traditional electrical elements. A
unique new set of models even allows users to interface hardware with a
SPICE simulation. The simulator, called ISSPICE4, is capable of simulating
all types of systems in various engineering disciplines. While SPICE
simulation is best known for electrical circuit simulation ISSPICE4 can
also simulate mathematical, mechanical, hydraulic, thermal, and physical
systems. 

A new interactive on-line help system provides users with extensive SPICE
syntax and problem solving help. The help is not simply a text listing,
but a true interactive environment where questions are answered with
movies, sounds, and graphics. Rather than simply displaying instructions,
the movies actually show the user how to perform a task. 

The schematic entry program included with ICAP/4, called SPICENET, has been
updated with new PCB layout interfaces, more support for mixed mode
circuits, an Orcad symbol/schematic translator, streamlined symbol
creation for subcircuit netlists and symbols and a Monte Carlo Wizard. The
revised symbol editor contains a Symbol Wizard that makes creating symbols
painless. Users will be allowed to import symbol artwork via the clipboard
and utilize Windows meta-files resulting in superior looking schematics. 

Another unique schematic feature is the ability to handle mixed-technology
or complex electrical designs via a multilayer structure. A schematic can
include electrical, mechanical, or mathematical objects, artwork, or
connections to real hardware. Schematic objects can then be mixed on
various layers to create various simulation scenarios. Users can specify
what layers to view, edit, print and simulate. This allows different
levels of complexity and connectivity to be easily manipulated. 

SPICENET has a very strong emphasis on simulation; much more emphasis than
traditional capture packages. SPICENET can actually function as a data
analysis and display tool. For example, SPICENET can display cross-probed
waveforms, node voltages, and other simulation quantities like FFTs,
currents, and device power dissipation directly on the schematic. The
displayed information is updated as the simulation runs. This often
eliminates the need to use a separate post processing tool for data
analysis. The result is greatly improved simulation performance and much
more useful documentation of the circuit design. 

The new version of ICAP/4 will be available in the 1 st quarter of 1996.
ICAP/4 is shipped with a protection dongle. However, a network version is
also available that DOES NOT require a protection device. ICAP/4 is the
only Windows SPICE package available without a hardware protection dongle.
