- Spice TR3e2bl is a 32-bit PC(386/486) shareware version of SPICE 3e2.
- Spice TR3e2 may be run in either interactive or batch mode, and is
- intended for anyone who may want learn how to use Spice thru
- interactive practice (i.e. trial and error) -> without spending lots of
- money for the honor.
-
- SPICE 3e2 (simulation program with integrated circuit emphasis version
- 3e2) was developed in the Electronics Research Laboratory at the
- University of California at Berkeley. Those who want the source code,
- or some real(?) documentation (the SPICE3 Version 3e1 User's Manual is
- the most useful), may call Berkeley at (510) 643-6687 and ask for a
- Research Software catalog.
-
- Spice is a general-purpose circuit simulation program for nonlinear
- dc, nonlinear transient, and linear ac analyses. Circuits may contain
- resistors, capacitors, inductors, independent voltage and current
- sources, four types of dependent sources, switches, transmission lines
- (both lossy and lossless), and the most common semiconductor devices:
- diodes, BJTs, and JFETs.
-
- Those who find Spice TR3e2 a great tool, but need more than basic Spice,
- may wish to spend lots of money on a commercial version of Spice.
-
- Those who continue using Spice TR3e2 should register it. See form at
- the end of this file.
-
- Spice TR3e2bl was complied using the Intel 386/486 C Code Builder Kit
- vesion 1.1. The stack size is set to about 1 meg byte, this may be too
- large for systems with 4-5 meg bytes RAM and may be too small for systems
- with more than 8 meg RAM. If this is a problem let me know.
-
- limitations:
-
- To keep the executable files small enough, only OP, AC, DC,
- transient, and fourier analysis are supported in Spice 3e2bl. Also,
- only the following device models are supported: resistors,
- capacitors, inductors, coupled inductors, linear sources, arbitrary
- non-linear sources, diodes, bipolar junction transistors, junction
- FETs, lossless transmission lines, lossy transmission lines, and
- voltage controlled switches.
-
- System requirements:
- a hard disk with at least 2 Meg free, a 386 or 486 with 4meg RAM,
- VGA display (for graphics), and a postscript
- printer (for hardcopy output). A math co-possessor
- is recommended.
-
- User requirements: Spice knowledge and/or trial and error
-
- files included on disk(s):
- spice.exe Spice TR3e2bl compiled with Intel's C Code Builder 1.1
- demo The demo command file
- *.cir sample circuits
- readme.doc this file
- spice3.doc a short spice manual
- news The Spice news file, read on startup in
- interactive mode
- lf156 a LTC subcircuit model
-
- *********** known bugs **************
-
- some notes from Berkeley:
- Models defined within subcircuits are not (always) handled correctly.
- Switch models, for example, must be defined outside of the ".subckt"
- and ".ends" lines or the model is not found.
-
- Sufficient detail is sometimes not preserved in transient analysis,
- use the "TMAX" parameter to avoid this problem.
-
- The base node of the bipolar transistor (BJT) is modelled
- incorrectly, use a semiconductor capacitor to model base effects.
-
-
- ************* DEMO information ********************
- Three demo circuits are included to help you get started. All three
- may be run by typing "demo<CR>" at the Spice prompt.
- DEMO.cir a 7th order Chebyshev filter (1db ripple)
- DEMO1.cir a third order elliptic active filter.
- DEMO2.cir an opamp with darlington power boost
-
- to exit Spice TR3e2bl, type "quit<CR>" while at the Spice prompt.
-
- ************* registration propaganda *************************
-
- Spice TR3e2b is released as shareware. It is intended for anyone who
- may want to do learn about spice and/or is willing to pay a
- registration fee. Remember that shareware is user supported software,
- and your support will make my life easier.
-
- To make support easy, three levels of support shall be graciously
- accepted.
-
- $0.00 ____ I'm too cheap but send money, but at least I
- will tell other people about Spice TR3e2.
-
- $45.00 ____ Spice TR3e2 is wonderful!! This seams to be a
- small price to pay for this software.
-
- for those with more money than sense:
-
- $1,000,000 ____ Spice TR3e2 is even better than since sliced bread!
- Rather than give the money to the people at
- Berkeley (who did almost all the Work), I want to
- help your retirement plan.
-
- $10,000,000 ____ We hate Spice TR3e2b.
- We are a commercial firm and we don't like the
- competition. Reformat your hard disk, burn all
- your spice documentation and move to Russia and
- teach THEM about joys of competition.
