README for misc utilities versions 2001*
(This software is ALPHA)
IMPORTANT
Please read the file NEWS for details on specifics for this release
- Installation
See the toplevel INSTALL for more instructions on general install
instructions
- Utilities
gmk_sym
Updated by Matthew Ettus, matt@ettus.com
Jerry's instructions below still work. There are
additional features for the first input line.
See TL16C554AFN.txt for an example of the extended input
Written by: Jerry O'Keefe, jerryok@pacbell.net
This is a simple utility to convert comma separated
descriptions into rectangular gschem symbols. It should
be useful for easily creating memory, processors or
connector style parts. All pin positions are in normal pin
spacing (300). Pin styles supported are line, dot-line,
and clock line. Pins can be placed on all sides of the
symbol's box. For example to place a dot-line style pin of
name INPUT at the normal pin 1 position of a IC would be:
INPUT,1,dot,L,1
The size of the symbol's box is also in pin spacings. So
a symbol with 6 inputs and 6 outputs would typically
require a size of: 3 for width and 7 for height.
See the included 7474.txt and 8031.txt as example files.
This utility is not strong on error checking and slotting
is not supported.
gmk_sym typical use:
./gmk_sym 7474.txt >7474-3.sym
gmk_sym is installed when make install is run.
smash_megafile
Written by: Mike Jarabek, mjarabek@playground.net
smash_megafile is a C program that will take a viewlogic
megafile and extract the contents into a directory of the same
name, with one file representing each element in the library.
This program should compile without any problems for anyone.
This program cannot create megafiles, it can just extract all
the contents. (Useful for say, extracting all the symbols from
a library...) Be aware that megafiles from PC versions of
ViewDraw use PC end of line terminations, it may be necessary
to use a program like dos2unix to convert the resulting text
files... before doing useful things with them.
smash_megafile typical use:
./smash_megafile megafile
where megafile is the name of a viewlogic megafile whithout
any extensions. The file megafile.lib and megafile.tbl must
exist in the same directory
smash_megafile is installed when make install is run.
convert_sym.c
Written by: Mike Jarabek, mjarabek@playground.net
convert_sym converts Viewlogic schematics and symbols into
geda format.
This utility should be considered a work in progress.
Be warned, the program has a few limitations:
1) Some text spacing may be lost due to the way that I
extract the text from the viewlogic records
2) Arcs in viewlogic are stored implicitly as a record
where the arc passes through three points,
the conversion from this format to geda's
center/radius/start/stop notation is not exact,
so some arcs may not render well.
3) Bubbles are drawn on pins that are negated. I believe
the code is correct, but have not tried all the
end cases.
4) Rotated and mirrored components may not show up correctly,
but should be better now, thanks to patches from
Thepthai Tabtieng <tabtieng@lsil.com>.
convert_sym (the C version) typical use:
convert_sym -s viewlogic_symbol.1 > viewlogic_symbol-1.sym
convert_sym viewlogic_schematic.1 > viewlogic_schematic-1.sch
convert_sym is installed when make install is run.
Thanks to Thepthai Tabtieng <tabtieng@lsil.com> for code to
support rotated and mirrored components, and a fix for
component instantiations.
