30 gnetlist is the netlist extraction/generation program which is part
31 gEDA (GPL Electronic Design Automation) toolset. This program takes a
32 schematic for its input and outputs a netlist.
34 gnetlist depends heavily on guile (a scheme based scripting language).
35 It uses guile to define the output format. Basically gnetlist reads a
36 schematic, creates an internal representation of the various connec-
37 tions, and then a guile script extracts the connections into some
40 gnetlist is very much so a work in progress. Currently it supports the

102 For more info on these formats please look at the README.*
104 Please read the official (non-existant) documentation on how to use
105 gnetlist, since this man page just describes the command line arguments
106 and a few examples on how to run gnetlist.
110 gnelist accepts the following options:
112 -q Quiet mode on. This mode turns off all warnings/notes/mes-
115 -v Verbose mode on. This mode gives as much feedback to the user
116 as possible. (optional)
119 Specify the guile procedure which is executed to create the
123 Specify the filename which will contain the netlist generated
124 by gnetlist. If this option is not specified the default file-
125 name is
"output.net
".
128 Specify a filename which contains scheme code to be loaded and
129 execute before any backend is loaded or any guile procedure
130 (using -g flag) is executed. This flag can be specified multi-
131 ple times and can be used to pass information to backends.
134 Specify a filename which contains scheme code to be loaded and
135 execute after the backend is loaded but still before any guile
136 procedure (using -g flag) is executed. This flag can be speci-
137 fied multiple times and can be used to pass information to
138 backends. This flag, for example, allows the user to override
139 variables inside of the backends (such as paths).
142 Pass the specified string to the guile interpreter. This
143 allows you to execute arbitrary guile scripts from the command
144 line. Be sure to surround the string with either single or
145 double quotes to satisfy your shell. The string is execute
146 before any init or netlist backend scheme code is loaded or
149 -I Put .INCLUDE
<filename
> in output file instead of model file’s
152 -i Interactive mode. After the schematic is read in and parsed
153 then go into interactive mode. Interactive mode allows the
154 user to execute guile procedures directly.
156 -s Sort output netlist (for Gnucap)
158 schematic1 [... schematicN]
159 At least one schematic file must be specified. If multiple
160 schematics are specified then they are sequentially read in and
161 parsed with the assumption that they are all part of the same
162 design. It is important that the schematic(s) follow all the
167 These examples assume that you have a stack_1.sch in the current direc-
170 gnetlist requires that at least one schematic to be specified on the
173 ./gnetlist stack_1.sch
175 This is not very useful since it does not direct gnetlist to do
178 Specify a guile procedure name to get gnetlist to output a netlist:
180 ./gnetlist -g geda stack_1.sch
182 The netlist output will be written to a file called
"output.net
"
183 in the current working directory.
185 You can specify the output filename by using the -o flag:
187 ./gnetlist -g geda stack_1.sch -o stack.netlist
189 The spice backend is run against the schematic(s) if you specify
190 -g spice and the tango backend is run if you specify -g tango.
192 To interact with the guile interpreter:
194 ./gnetlist -i stack_1.sch
196 You will get a prompt where you can execute guile procedures.
198 To get a more verbose feedback as to what gnetlist is doing run
201 ./gnetlist -v -g geda stack_1.sch
205 No environment variables are used.
