Getting More Information About the Fuse Models
*****
For technical information describing the models and application
notes on how to use the models, please see the Intusoft April 1991
newsletter and the publications "Simulating With Spice" and
"Spice Applications Handbook", both available from Intusoft.
***** STRUCTURE *****
The Intusoft Newsletter floppy consists of three subdirectories.
CIRCUITS - containing SpiceNet schematics & SPICE netlists (Note:
some of the netlists (.CIR) contain extended SPICE syntax understood
only by Intusoft software. Circuits with a .CKT extension are Berkeley
SPICE 3E.2 or Berkeley SPICE 2G.6 compatible.
MODELS - Contains .LIB files with models/subcircuits using Berkeley
SPICE 3E.2 or Berkeley SPICE 2G.6 syntax.
SYMBOLS - Contains new SpiceNet schematic symbols
All netlist/library files use an ASCII format.

***********************
Using The Models
**********************
**** To use the fuse models:
** If you have any Intusoft software,
This library is already included in PreSpice version 3.x.
The symbols are already included with SpiceNet version 3.x.
** If you are using another SPICE compatible simulator,
(other than IsSpice)
The SPICE compatible subcircuit models for the fuses
are in the ASCII files THERMAL.LIB. Just paste the subcircuit
netlist for the desired fuse into your SPICE input netlist
file using your favorite netlist editor. The subcircuits are
usable with any Berkeley SPICE 2G.6 compatible simulator.
