ICAP/4Windows Demo 8.x.10 Build 2127 (25 Meg Download) limitations listed below:
Includes 30 Power Supply Templates from ON Semiconductor.

- The ICAP/4Windows Demo has a 20 Parts Simulation limit. If you place more than 20 parts on the schematic or place a subcircuit model made up of more than 20 components, the Demo simulator will stop with a "too complex" message when you try to simulate your circuit.

- 1,252 models are included in the Demo out of the 18,000+ available from Intusoft
(See model list or product comparison for which models available in each package)
Note: No Demo limit placed on adding your own SPICE3 compatible models.

- Explore "GFT," a truly cutting-edge modeling technique for measuring open loop properties in a closed loop without breaking the loop. Valuable for the design of power electronics, ICs, servo systems…any loop configuration. Its creator, Dr. R. David Middlebrook with California Institute of Technology, also presents a wealth of techniques for successful SPICE simulation. The ICAP/4Windows demo includes GFT Templates, and also a User's Manual written by Dr. Middlebrook.

- Scope5 Demo will not allow you to use a text file of data points as a source.

- Scope5 Demo will not allow you to read in touchstone files and plot smithcharts.

ICAP/4 Documentation (10.7 Meg Download)
Includes the IsSpice4 User's Guide, Working with Model Libraries, and the Power Supply Template instruction sheet. The IsSpice4 book contains a complete syntax reference guide to IsSpice4 with data on the advanced analyses, model parameters, and Interactive Command Language (ICL) scripts. Wokring with Model Libraries contains information and equations for the key IsSpice4 semiconductor models and subcircuits. The Power Supply Template instruction sheet goes through an example circuit to show the capability of our software.

Magnetics Designer Demo Software

Magnetics Designer Demo 4.1.0 Build 344 (4.7 Meg Download) limitations listed below:

- Demo comes with fixed Fair-Rite Core Library(Subset of our extensive Fair-Rite Core library, and you can not add MORE Cores to Demo Version).
Note: The actual software allows you to easily add any core you want and includes many thousands of cores from different vendors.

- Demo limits you to only 2 windings.
Note: The actual software allows you to have 32 windings.

- The ability to save is disabled in Demo.

- The ability to produce summary and winding reports is disabled in Demo.

- SMPS wizard for creating Forward, Push-Pull, and Bridge Buck regulators using the transformer tab is disabled in Demo.
Note: The SMPS wizard for creating transformer coupled Flyback designs using the inductor tab is available to show how the SMPS wizards work.
