21 Jerry's instructions below still work. There are
22 additional features for the first input line.

27 This is a simple utility to convert comma separated
28 descriptions into rectangular gschem symbols. It should
29 be useful for easily creating memory, processors or
30 connector style parts. All pin positions are in normal pin
31 spacing (300). Pin styles supported are line, dot-line,
32 and clock line. Pins can be placed on all sides of the
33 symbol's box. For example to place a dot-line style pin of
34 name INPUT at the normal pin 1 position of a IC would be:
38 The size of the symbol's box is also in pin spacings. So
39 a symbol with 6 inputs and 6 outputs would typically
40 require a size of: 3 for width and 7 for height.
42 See the included 7474.txt and 8031.txt as example files.
44 This utility is not strong on error checking and slotting
49 ./gmk_sym 7474.txt >7474-3.sym
51 gmk_sym is installed when make install is run.

58 smash_megafile is a C program that will take a viewlogic
59 megafile and extract the contents into a directory of the same
60 name, with one file representing each element in the library.
61 This program should compile without any problems for anyone.
62 This program cannot create megafiles, it can just extract all
63 the contents. (Useful for say, extracting all the symbols from
64 a library...) Be aware that megafiles from PC versions of
65 ViewDraw use PC end of line terminations, it may be necessary
66 to use a program like dos2unix to convert the resulting text
67 files... before doing useful things with them.
69 smash_megafile typical use:
71 ./smash_megafile megafile
73 where megafile is the name of a viewlogic megafile whithout
74 any extensions. The file megafile.lib and megafile.tbl must
75 exist in the same directory
77 smash_megafile is installed when make install is run.

86 This utility should be considered a work in progress.
87 Be warned, the program has a few limitations:
89 1) Some text spacing may be lost due to the way that I
90 extract the text from the viewlogic records
92 2) Arcs in viewlogic are stored implicitly as a record
93 where the arc passes through three points,
94 the conversion from this format to geda's
95 center/radius/start/stop notation is not exact,
96 so some arcs may not render well.
98 3) Bubbles are drawn on pins that are negated. I believe
99 the code is correct, but have not tried all the
102 4) Rotated and mirrored components may not show up correctly,
103 but should be better now, thanks to patches from
104 Thepthai Tabtieng <tabtieng@lsil.com>.
107 convert_sym (the C version) typical use:
109 convert_sym -s viewlogic_symbol.1 > viewlogic_symbol-1.sym
111 convert_sym viewlogic_schematic.1 > viewlogic_schematic-1.sch
113 convert_sym is installed when make install is run.
115 Thanks to Thepthai Tabtieng <tabtieng@lsil.com> for code to
116 support rotated and mirrored components, and a fix for
117 component instantiations.
120 Sarlacc (consists of sarlacc_schem and sarlacc_sym)
121 Written by: Matthew Ettus
123 Sarlacc is an OrCAD to gEDA format schematic converter. This software is
124 beta, so it still has limitations. To convert files do the following:
126 * Go into ORCAD, load up your schematic, and save it as "SDT IV format".
127 All of the versions of ORCAD should be able to do this. This
128 is the old ORCAD 16 bit format. In this process, your library parts
129 will be converted to a new format. Along the way, there is an
130 intermediate format which is all text. It is probably kept in your
131 tmp directory (C:\windows\temp ?), and it has a .src extension.
133 * To convert schematics type: sarlacc_schem orcadfile > gedafile.sch
134 * To convert symbols type: sarlacc_sym orcadlibrary.src
135 This will create individual .sym files for gschem. You will need to
136 put them somewhere gschem will find them

142 olib is a simple automated converter from OrCAD(tm) v4 (in SDT version
143 1.10) parts library (in ASCII dump format, through "decomp" utility)
144 to gEDA component definition in .sym format file.
150 refdes_renum reads a gschem schematic file or files and renumbers
151 all reference designators. The reference designators are numbered
152 starting with 1 and the old schematic file is replaced by the modified

162 tragesym is a symbol creator for gEDA/gaf. The aim of this python
163 script is to make it easier (and faster) to create symbols for gEDA.
167 * create pins and arrange their elements (clocksign, dot, type, pinnumber,
169 * sort pins alphabetical and numerical
170 * swap words of pinlabels if wished
171 * draw negation lines on the labels
172 * rotate pinlabels if wished
173 * some syntax check to the input file
175 Please see the README.tragesym and ChangeLog.tragesym for more info.
176 Be sure to look at the examples in examples/tragesym. There you will
177 find the template.src file referenced in the README.tragesym file.
183 A perl program which implements backannotation from Pads PowerPCB
184 board layouts to gschem schematics.

193 gsch2pcb is conceptually based on the gschem2pcb shell script
194 distributed with gnetlist, but additionally handles multiple
195 schematics, handles element file footprints, and removes pc board
196 elements corresponding to components deleted from the schematics.
197 It also forward annotates component value changes.
199 Please see the README.gsch2pcb file for more information. Also see
200 examples/gsch2pcb/project.sample for an example of a project file.
206 This program is used to create a gEDA design archive. It operates
207 in two modes: archive mode and extract mode. In archive mode it
208 creates a project archive from a bunch of project files, and in
209 extract mode it extracts the files from the archive and places them in
212 garchive requires python to run.
213 Run: garchive -h for help information.
