Newsletter Discusses SPICE 3 Behavioral Modeling

	The Intusoft Newsletter is a unique FREE publication dedicated to discussing topics related to the SPICE circuit simulation program.  The November 1995 contains several application notes designed to help engineers simulate circuits more effectively.

	The first application note discusses the Berkeley SPICE 3 B (behavioral) element in detail. It describes several new behavioral modeling functions that Intusoft has added to the element as part of IsSpice4, the companie's SPICE 3 simulator.  The B element replaces and expands upon the polynomial functions found in SPICE 2.  Several examples are provided showing how to model time, frequency, and temperature depedent elements.

	The second article discusses transient voltage suppression devices.  Two models are presented for a MOV(metal oxide varistor). One uses SPICE 2G syntax while the other uses SPICE 3 syntax.  The SPICE 3 version uses behavioral modeling function to provide a more accurate response than the 2G version.  A free software utility is described that allows designers to create MOV models from data sheet parameters. The utility is available free of charge via Intusoft's Web site. 

	The Intusoft Modeling Corner, a regular column in the newsletter, includes a description of a realistic capacitor model.  The model is made up of elements that are frequency, DC bias, and temperature dependent. The model also includes all relevant parasitics. Several example models for different capacitor from Kemet Electronics and the Intusoft Tech support team are presented.

	In the November issue of the Intusoft Newsletter, Intusoft introduces a new and unique SPICE modeling product called SALT, or SPICE Array Linking Technology.  Among other things, SALT enables IsSpice to link directly to hardware data acquisition boards using OLE technology; a first time achievement for any simulator in the EDA industry.

	A floppy disk containing all of the schematics and SPICE models in the newsletter along with new op-amp models from Comlinear, new Power Mosfet and IGBT models from Harris and Omnirel, plus over 125 varistor models, created by Intusoft's support staff, is available for a nominal fee.

	The Intusoft Newsletter is the only regularly scheduled publication dedicated to SPICE modeling and analog circuit simulation.  An electronic version (Replica document) of the Intusoft Newsletter is posted on Intusoft's Web site (http://www.intusoft.com) and on CompuServe (CADD/CAM/CAE vendor forum). The peak newsletter circulation is currently at 34,000 readers in over 110 countries.
