16.SH DESCRIPTION
17.B Vis
18is a system for formal verification, synthesis, and simulation of finite state
19systems. It has been developed jointly at the University of California at
20Berkeley and the University of Colorado at Boulder.
21.PP
22Vis is primarily used interactively, using a prompt system.  Most help on its
23commands is given within vis: type
24.B help
25at the vis command prompt.  The
26.I examples
27directory gives some examples of how
28to use vis.  The definitive documentation resides at the Vis Home Page.  This
29man page concentrates on the command options.
30.PP
31Vis works interactively if invoked without any options.  Vis can also be called
32in batch mode, using
33.B -c
34or
35.B -f.
36In this case, either
37.B -x
38needs to be specified, or the last argument needs to denote a file.
39.PP
40The case in which
41.B -x
42is not specified is only used in practice for synthesis.
43.I File
44is read before the script is executed, and after execution another file is
45written.  The details are determined by the
46.B -t, -T,
47and
48.B -o
49flags.  It is probably easier to incorporate the reading and writing
50of the file in the script.
51.SH OPTIONS
52.TP
53.B  \-\^c cmd
54 Execute VIS commands `cmd'.
55.TP
56.BR  "\-\^f " file
57Execute script containing vis commands
58.TP
59.B  \-\^h         
60Print the command usage
61.TP
62.BR "-\^o  " file
63Specify output filename (default is -)
64.TP
65.B \-\^s
66Do not read any initialization file.  If not specified, the files
67.I $VIS_LIBRARY_PATH/master.visrc,
68and
69.I $HOME/.visrc
70are executed in that order.
71.TP
72.B \-\^t type
73 specify input type (blif_mv (default), blif, or none)
74.TP
75.B \-\^x
76Equivalent to '-t none -T none'
77.\"
78.SH EXAMPLES
79.TP
80.B vis\^
81Calls vis interactively
82.TP
83.BI "vis -x -f " file\^
84Executes the named vis script.
85.\"
86.SH FILES
87The scripts
88.I $VIS_LIBRARY_PATH/master.visrc,
89and
90.I $HOME/.visrc
91are read in that order before any other script executes.  They are used to
92define aliases and the like.
93.\"
94.SH ENVIRONMENT
95.B $VIS_LIBRARY_PATH
96determines the location of the master visrc file and the help files.
97.\"
98.SH NOTES
99Vis will produce line-buffered output if you set vis_stdout and
100vis_stderr from the vis prompt.  In any case, you can force vis to
101flush the output by sending it a USR1 signal, using kill.
102.\"
103.SH BUGS
104For optimum performance, set the
105.B datasize limit
106to a reasonable size (such as something less than the amount of RAM
107you have).
