If you are currently on maintenance, you can also obtain this update via the web. Simply go to
http://www.intusoft.com/support.htm and enter your serial number to obtain this update. Your serial
number is on the “Installation Letter” that came with your initial purchase. You can also find your
serial number from the Help pulldown, “About SpiceNet,” then the User Tab dialog within the
Schematic program. (Note that the ICAP/4Students package does not offer maintenance.) Should
you have any questions about the status of your maintenance program, please contact Intusoft at

New Features and Enhancements
http://www.intusoft.com/featurechanges.htm for a more detailed list.
New schematic file format: Version 15 is new and able to directly
accommodate drawing artwork, work with new convergence options
(ICSTEP and AUTOTOL) and provides a subcircuit current test point
via the keyboard (6y). For users on a previous version of ICAP/4,
8.x.11’s new features will be lost because the drawing will save to
the older version.
SpiceNet Artwork Drawing tools: Drawing tools have been added
directly into SpiceNet. Artwork includes line, bezier, poly-line,
rectangle, round rectangle, ellipse and polygon. Artwork can be
dragged and combined. When drawing the above shapes, constraint
capability can be selected, which proportions a shape as it’s drawn.
Save Symbol Editor Preferences: The ability to save Symbol Editor’s
window and tool palette position has been added. Likewise, settings
prescribed in the editor’s Options menu can be saved.
Modify Wire Widths Displayed on Schematic: Wire widths can be
modified for improved visibility, also advantageous for printing. Wire
widths are not scaled when the drawing is rescaled on the monitor.
Place Parts Easily: The “Preferred Parts” hierarchical menu has been
added to the right-button popup menu.
Automatic Test Point Ref Des Assignment: A Test point is
automatically assigned a name based on the node or part name it is
attached to during initial placement. Test point names are preceded
by a V, I or W for voltage, current and power respectively.
Systematically Reassign Ref Des: Any or all part reference
designations can be renumbered by starting from 1 for each part type, or
by renumbering any part type based on the Ref Des of first chosen part.
Also, Ref Des are retained when copying and pasting, as long as
prior designations do not already exist on the target drawing.
Subdrawing Management: For a subdrawing of the active project,
you are queried whether you want to simulate the current project, or
change the project to the active window before simulation. It is no longer
necessary to navigate back to the project window before simulation.
New Convergence Parameters: Entries for AUTOTOL and ICSTEP
have been added to “Simulation Options” dialog.
After Simulation Go To: A new dialog enables the SpiceNet window
or IntuScope waveform window to be assigned as the active application
after a simulation is complete. This can be selected anytime from the
Options menu in the IsSpice4 window.
New Acct. Output: Added "Maximum Transient Iterations (MTI)
and "MTI Time" to report the maximum iterations during simulation,
and the simulation time step where they occurred.
New IntuScope Scripts: “Delta” acquires dy/dx values from
IntuScope’s cursors. "ExtractMid" and "ZapDelay" rid start-up
transients before performing an operation such as an FFT. They work
by extracting elements from a vector array. ExtractMid’s dialog enables
a desired default scale range for extraction, and plots the new vector.
ZapDelay subtracts the offset, starting the new vector at 0.
Display More Log Divisions: IntuScope now displays major division
lines and numeric labels in logarithmic scales containing three or
less cycles, for intervals of 1, 2, and 5, rather than just at the beginning
of each cycle (i.e. intervals of 1) as before.
Placed Cursors Keep Position: Cursors in IntuScope are no longer
reset to end points when you add new waveforms, or update existing
waveforms in a plot.
New SPICE Models: 622 models have been added to ICAP/4’s complete
library, mainly from user requests. A variable-area transistor model has
been added, useful for IC design, plus two generic NMOS and PMOS
models for power FETs. These account for sharp MOS capacitance
change near threshold, and Rdon temperature coefficients for design
that senses current via the ON voltage.
New IBIS2SPICE Converter: This is only available for non-Rx ICAP/4
products. It supports all 14 IBIS model types and IBIS versions through 3.2.
Added Support for Pspice Diode Parameters: Intusoft’s diode model
now support the six extra parameters used by Pspice: ibvl, ikf, isr, nbv,
nbvl, and nr. If these are not defined, then Intusoft’s diode model
reverts back to using its standard Berkeley version.
Updated BSIM models: New BSIMSOI3.1 assigned to level=10.
New BSIM4.3.0 assigned to level=15. BSIM4.2.1 still at level=14.
Enhanced Library Manager: Several enhancements have been made,
and it’s been added to all non-ICAP/4Rx software packages.
Part Number Validation: Implemented the ability to build and verify
the NPSL (NASA Parts Selection List) part numbers for resistors
and capacitors. MIL-STD parts are a subset of the NPSL.
Export to Bartels PCB system: A graphical interface has been added
to assign a wealth of footprint information in SpiceNet, such as passive
part type, mechanical properties, pin assignment, failure rate, and
terminal type. Designs can be exported to Bartels’ PCB system.
