SPICE模拟器设备参数手册说明书

Computer Exercises Manual:
Device Parameters in SPICE
This manual is provided as a PDF¯le{just click on cem.pdf to open it.This can be done from the CD(using Windows Explorer, click on the CD-drive symbol to see the¯les,and double click on cem.pdf),although you may wish to copy the¯le to a selected folder/directory on your hard disk,and to run it from there.
Interactive MATLAB Animations for
Understanding Semiconductor Devices
This tool is in the form of linked\M¯les"that can be run by typing usd
in the MATLAB control window.The\M¯les"are placed in the MATLAB folder/directory of this CD.The minimum requirement is the Student Edition of MATLAB5.0,and obviously the new Student Version of MATLAB and any professional version higher than5.0 can be used.More information on MATLAB is available from The MathWorks,Inc.

Type usd<ENTER>in the MATLAB control window,and a properly setup MATLAB will respond with the following control window for the animations:
INTERACTIVE MATLAB ANIMATIONS FOR Understanding Semiconductor Devices
Oxford University Press, New York, 2000.

Griffith University The next page provides setup instructions/suggestions,whereas the following pages provide illustrations of selected -plete list of the animations appears on the last page.
INSTRUCTIONS/SUGGESTIONS FOR SETUP OF THE MATLAB\M FILES"
1.It is suggested to create a new folder/directory on your hard
disk for the\M¯les"(*.m¯les).For example,using the
Windows Explorer create a new folder on the c:drive,called
usd(File!New!Folder,and then type usd to rename it.)
2.Copy the\M¯les"from the matlab folder/directory on this
CD to the newly created folder/directory on your hard disk.
NOTE for UNIX users:Make sure that the¯lenames are
in lower-case font(bjt usd.m is correct;BJT USD.M will not be
found by the master¯le).
3.Setup a path in MATLAB so that it can¯nd the newly copied
¯les:
Open MATLAB and select File!Set Path from the
MATLAB control window.This will open Path Browser
window,where you select Path!Add to Path,and
type the directory to be added(c:n usd).
4.Run the animations by typing usd in the control window of
MATLAB.
