This package includes the source for "cif2ps," a program to create a
PostScript representation of an integrated circuit from a layout
stored in Caltech Intermediate Form (CIF).  A README, Makefile, and
manual page are included as well as some sample CIF files.

This version was derived from a version distributed by Marc Lesure
of Engineering Computer Services, Arizona State University.
The original version (called "cifp") was written by Arthur Simoneau,
of The Aerospace Corporation, El Segundo, California.

My additions to this program include:
run time customization of plot styles for all CIF layers, limited
plot depth option, technology-independent handling of CIF layers,
PostScript functions for filling an object using a clipping path,
automatic ordering of drawing operations for minimal obliteration,
reduced output size, and support for CIF objects other than boxes.

A few test files are included.  Running "make test" will generate a
layer-key for Scalable CMOS (SCMOS).  The file "everything.cif" has
one object of each CIF type: a box, roundflash, polygon, and wire.
The file "scmos-test.cif" is a sample layout from the old "cifp."

This version of "cif2ps" is distributed without any promise of
support, though I would appreciate bug reports and changes.

[ README file from Marc Lesure's version of "cif2ps":  -GWR ]

This code was originally written by Arthur Simoneau, The Aerospace
Corporation, El Segundo, California. and was called 'cifp'.  'cifp' would
only take MAGIC SCMOS cif input and generate postscript for a single
page of output.

I've since taken it and modified it to accept cmos-pw technology for
our local needs at Arizona State University.  The biggest improvement
I made was to get multiple page output.  Each page is numbered with
(x,y) coordinates so you know its proper sequence.  Also each page
overlaps with its neighbor, so you can cut and paste if you want.
The program will rescale the user-specific scale to avoid producing
blank pages.  A scaling limit of 5 by 5 has been put in the program to
eliminate massive outputs.  Cif2ps can generate a postscript file in
the multi-megabyte range very easily.  I renamed the program to
'cif2ps' to be more descriptive of its function.

Two test files have been included, cmos-pw.test.cif and scmos.test.cif.
The file cmos-pw.test.cif was generated using the IGS2CIF program
version 2a.04 on a HP EGS Graphics system.  The file scmos.test.cif is
from the original 'cifp' distribution.  To plot this file you must use
the '-T' option on 'cif2ps'.

[ The "-T" option is no longer needed or available.  -GWR ]

Cif2ps is now used here in place of cifplot from the Berkeley VSLI
distribution.

If somebody wants to modify this code you should be aware that the
order of the "filled boxes" are important.  The last filled box wins
all of the pixels and so improper order can cause the p-well to
obliterate all of the CIF geometries.

[ Filled objects are now handled in a more sophisticated manner. -GWR ]

I will be maintaining this code and adding missing features as they
become desirable, so instead of re-inventing the wheel you should
contact me before making any changes to see if I have already done
them.  Also, I would like to maintain knowledge of where this code is
so I would appreciate any new sites request the code from me rather
than siphoning it from another site.

I will gladly respond to any bug reports if a suitable example
displaying the bug is sent to me.
