Finally, there is a simple program available to alleviate the difficulties of SPICE
model development. S PICE M OD , the
SPICE modeling spreadsheet, gives
you the power to create an unlimited
number of SPICE models for thousands
of semiconductors. With SPICEMOD, you
won't have to curtail or eliminate your
simulation activities because you don't
have a model, you won't have to spend
countless frustrating hours learning the
intricacies of SPICE model parameters,
and you won't have to make any laboratory measurements. All you need is the
manufacturer's data sheet and just a few
minutes of your time.
SPICEMOD produces accurate models
that can be used with any Berkeley
SPICE compatible program. File storage is in an ASCII format insuring easy
file transfer and editing. Nothing is hidden. All models and subcircuits are
available for viewing and editing. And
because model development is so
streamlined, you can develop minimum,
maximum, typical or worst case libraries
to cover all of your simulation needs.
SPICEMOD is integrated with ICAPS,
Intusoft's menu shell program and
PRESPICE, Intusoft SPICE pre-processing program. The models and subcircuits created in SPICEMOD can be stored
in .LIB files compatible with Intusoft's
PRESPICE program. This allows all the
developed models to be immediately
used in your SPICENET schematics and
ISSPICE circuit simulations.
A comprehensive set of test circuits is
included (SPICENET schematics, ISSPICE
netlists, plus hardcopy documentation
and instructions). They can be used to
characterize and evaluate your models,
providing feedback on the accuracy of
the model and directions on what areas
of the model may be tweaked for greater
accuracy. The circuits will allow your
SPICE program to produce the same
curves and graphs seen in manufacturer's data sheets.
* Models for RF frequency Bipolar transistor are available separately from Intusoft.

SPICEMOD, Modeling Made Easy
SPICEMOD is an easy to use program employing a simple spreadsheet format to generate
accurate SPICE models from manufacturer's data sheet parameters.
How SPICEMOD Functions
SPICEMOD understands both data sheet parameters and SPICE
model parameters. It also understands how to convert from
one to the other. As data sheet values are entered, they are
immediately analyzed and the proper conversions to the
SPICE model or SPICE subcircuit parameters are displayed.
The more data you enter, the more accurate the model will be.
However, if only limited data is available, SPICEMOD will make
estimates for the remaining data based on the data you have
entered.
Custom Subcircuits
Some common semiconductors such as Power Mosfets and
Power BJTs cannot be modeled with the basic SPICE .MODEL
statement. A subcircuit approach using several elements
must be used. Although some SPICE model vendors try, use
of the .MODEL statement alone will not allow critical dynamic
parameters and parasitics to be properly modeled. That's
why Intusoft has placed several custom designed subcircuit
representations for these devices in SPICEMOD.
How To Use SPICEMOD
First, select a device to model. You may select from:
• Diodes,
• Zener Diodes
• Transistors,
• Power
Transistors,
• Darlington
Transistors,
• JFETs,
• MOSFETs, and
• Power MOSFETs
• SCR or GTOs
• IGBTs
Then, enter as much data as you can. You will see the model
update as data values are entered or changed. If you do not
have some of the values SPICEMOD will make estimates. This
feature is most important since the ability to estimate values
allows SPICEMOD to always create a realistic SPICE Model
even if only the minimum information is entered.
That's it !! When you exit the data entry screen your model will
automatically be saved in a file of your choice. You may also
save the model in the Intusoft .LIB (ASCII) format, ready for
use with the rest of Intusoft's circuit design tools.
A Minimum Amount Of Learning Is Required
SPICEMOD contains a complete on-line help system with
information on the data sheet parameter requirements and
the SPICE model and subcircuit parameters produced. Critical equations detailing device operation are also given.
Making And Editing Libraries
Creating libraries of device models is easy since SPICEMOD
can search old files for models and update or add to them as
desired. This will allow you to build on the SPICEMOD models
and add any non-standard SPICE parameters that your
simulator may require.
SPICEMOD accepts common data sheet parameters available from most manufacturers.
Minimum data specifications for a model are listed in bold.
