Hi,


thanks for your interest in SPICECAD.

SPICECAD is delivered as an executable program. It can be installed
whereever you want.
SPICECAD is split into two files:

spicecad-1.VER.REL.tar.gz   contains the manual and example files

spicecad-1.VER.REL-linuxelf-eval.tar.gz contains the linux evaluation binary.
spicecad-1.VER.REL-sunsol-eval.tar.gz contains the SUN SOLARIS  evaluationbinary.
spicecad-1.VER.REL-sunos-eval.tar.gz contains the SUNOS 4.1.4 evaluation binary.





Use 'tar xzf  spicecad-1.VER.REL.manual.tar.gz ' to unpack the documentation
and example files.
Use 'cd INSTALL_PATH ; tar xzf  spicecad-1.VER.REL-PLATFORM.tar.gz'  to unpack the
executable.

If you do not have tar with decompression capabilities,
type

'gzip -c -d  spicecad-1.VER.REL.manual.tar.gz | tar xf - ' 
'gzip -c -d  spicecad-1.VER.REL-PLATFORM.tar.gz | ( cd INSTALL_PATH ; tar xf - ) ' 


The tar file containing the binary should be untarred  
at a place where  the SPICECAD binary shall be installed.


Several directories will be created by tar when untarring the file 
spicecad-1.VER.REL.manual.tar.gz  :

'spicecad' is the main directory

Subdirectories are:

'spicecad/examples':         containing example designs and other subdirectories
'spicecad/doc':              containing the manual 'manual.ps'
'spicecad/doc/MANUAL_HTML':  contains the manual in HTML format.
'spicecad/bin':              containing some additional scripts,
                             but not the binary. The SPICECAD binary
                             can be moved manually to this place.
                             Do not forget to set the search path
                             to this directory.
'spicecad/helpfiles':        containing SPICECAD online help files


In 'spicecad/bin' , there are two script files called 'run_titan' and
'run_hspice' which call HSPICE or TITAN if you have purchased these
simulators. The default simulator is SPICE3, which is hard linked
to the SPICECAD binary, and which is used by default. 
If you have an HSPICE simulator on your machine,
you can use this simulator instead of the built-in SPICE3F4.
So, copy 'run_hspice' to a place where your search path points to,
and enjoy the cross-probing capabilities of SPICECAD and HSPICE .



Now, you are ready to start your first SPICECAD session.

To run the examples, change into directory 'spicecad/examples' 



After having set your PATH - variabe, call

spicecad  ( or spicecadstat , spicecad.so, spicead.sunos) ... whatever the 
                                                              name of the binary is)

Please do not  type  

spicecad &   , this will not work

Then,  wait for the spice3f4-prompt. Type

cad -c first

to load the first example schematic. 

Then, the first example schematic window will pop up containing passive elements.
You should be able to run a simulation immediately
without placing any more elements. When you look close to the
contents of all the rectangular green boxes, you will see
so-called simulation boxes (smallsig), parameter boxes  and
option boxes . These boxes contain control  information for
SPICE3. Now, pull down the pulldown simulation menu and hit 'runsim'.

Now, you can select a net using  "select V(x)" .
Click at a net using the left mouse button and finish the
selection  with a click on the right mouse  button. 
Now, you can plot  hitting 
Plot data .......  -> plot acm  (ac magnitude)
A plot window pops up automatically  displaying the
small signal simulation results using linear axes.
Please click onto the plot window using the right mouse 
button. A pop-up menu will come up displaying measures
to change the look of the curve.
Please hit 'loglog'  to change  to double-logarithmic
display. 





Afterwards, print and read the  manual to learn the tricks.

WARNING 

A file .spiceinit can be found where the example schematics
are stored. If you create you own design directory, please
do not forget to copy .spiceinit into this directory
before you start SPICECAD. Otherwise, a segmentation violation
might occurr.
