- XSPICE Press Release

- Georgia Tech Research Corporation
-
-
- XSPICE, introduced at the 1992 International Symposium on Circuits and
- Systems (ISCAS), is an extended and enhanced version of the popular
- SPICE analog circuit simulation program originally developed at the
- University of California at Berkeley. XSPICE was developed at the
- Georgia Tech Research Institute (GTRI) as a tool for simulating
- circuits and systems at multiple levels of abstraction. XSPICE permits
- a user to simulate analog, digital, and even non-electronic designs
- from the circuit level through the system level in a single simulator.
- A special Code Modeling feature allows users to add new models
- directly into the simulator executable for maximum simulation speed
- and accuracy. Code models are written in the C programming language
- allowing arbitrarily complex behavior to be described. Code model
- development tools are provided to simplify the process of creating new
- models, compiling them, and linking them with the XSPICE core.
-
- XSPICE provides a rich set of predefined code models in addition to
- the standard discrete device models available in SPICE. The XSPICE
- code model library contains over 40 new functional blocks including
- summers, multipliers, integrators, magnetics models, limiters,
- S-domain transfer functions, digital gates, digital storage elements,
- and a generalized digital state-machine.
-
- Digital functions are simulated in XSPICE through an embedded
- event-driven algorithm added to the SPICE core. This algorithm is
- coordinated with the analog simulation algorithm to provide fast and
- accurate simulation of mixed-signal circuits and systems. The
- event-driven algorithm supports a new "User-Defined Node" capability
- allowing additional event-driven data types to be defined and used.
- XSPICE comes with a 12-state digital data type as well as a
- user-defined node library that includes 'real' and 'integer' types
- useful in simulating sampled-data systems such as Digital Signal
- Processing algorithms.
-
- XSPICE is currently available for UNIX workstations and is supplied in
- source code form allowing users to customize and extend the simulator
- and models to particular needs. To date, the simulator has been
- successfully compiled and used on HP Apollo and Sun workstations. The
- XSPICE simulator and User's Manual are available with a cost-free
- license arrangement from the Georgia Tech Research Corporation for a
- distribution charge of US $200 (including first class postage within
- the U.S.A.; an additional US $25 is required for overseas delivery by
- air). For further information, please contact the Office of Technology
- Licensing, Georgia Tech Research Corporation, Georgia Institute of
- Technology, 400 Tenth Street, Atlanta, GA 30332-0415, USA, or phone
- (404) 894-6287 (voice) or (404) 894-9728 (FAX). Internet users may
- send email to XSPICE@GTRI.GATECH.EDU to obtain copies of the order
- form and license agreement (please include the word "license" in the
- subject header when mailing to this address).
