NAME

olib - OrCAD(tm) library part to gEDA .sym converter

SYNOPSIS

olib filename prefix

DESCRIPTION

olib is a simple automated converter from OrCAD v4 (in SDT version 1.10) ASCII parts
library to gEDA component definition in .sym format file. It allow an initial dumb
conversion file to file, with one lib converted in multiple .sym file, one per component
in library. The converted component file may need a little editing to become usable, but
in some case needs no editing at all. olib will write one file per part in the current
directory.

olib will:

· Convert box-shaped components in OrCAD lib to .sym file in gEDA format;

· Place pin, pin name, pin type, pin number;

· Place logic bubble when needed (DOT attribute in OrCAD (TM), for logic negation);

· Place clock arrow when needed (CLK attribute);

· Place reference, from REFERENCE statement in OrCAD;

· Place part name as label and device name as attribute;

· Parse and draw non-box component, with LINE, ARC, CIRCLE and TEXT;

· Add power pin as invisible net=name:pin attribute when detected (in OrCAD,
invisible pin has typically T0 and B0 coords);

· Through a command line switch, hides pin name in VECTOR drawn symbols, for a better
appearance;

· Write both new (post-20020825) and old (20020209) file format for .sym files
through a switch on the command line;

OPTIONS

filename
The OrCAD library to convert. This should have been previously converted to ASCII
format using the OrCAD 'decomp' utility.

prefix The prefix used to generate the filenames of the output gEDA symbols e.g. prefix-
partname-1.sym

LIMITATIONS

olib has the following limitations:

· olib will not parse and store alternate component drawing (statement CONVERT in
OrCAD);

· olib will not handle drawing part using VECTOR list from another part (statement
VECTOR 'partname' in OrCAD);

· olib will not handle FILL statement in VECTOR statement (no equivalent in gEDA);

· olib will not handle multiple part in one package (slots in gEDA).
