NAME
pggen - generate a pattern generator tape
SYNOPSIS
pggen
[
-s
]
[
-n
name ]
[
-c
x_center y_center ]
[
-t
x_trans y_trans ]
pattern_file
DESCRIPTION
pggen takes
pattern_file,
the output file from
ciftomann(1),
and produces a Mann-3000 format pattern generator tape consisting
of a directory file and then a separate file/mask for each layer.
When the command is executed,
pggen
makes one pass over the output to build up a directory
and compute the bounding box for the chip. At this point it
prints `Hit return when the tape is ready : '.
Someone must now physically mount a tape on the tape drive.
After verifing that the tape drive is ready, hit return and
the program will then create the pattern generator tape.
pggen
takes the following options :
- -s
-
pggen(1)
normally produces various short messages as each stage is
started. The
-s
option suppresses them.
- -n name
-
The name for each mask in the directory is of the
form 'name<layer name>'. If not specified,
name
defaults to your login name.
- -c x_center y_center
-
The masks are centered about the point
(x_center, y_center),
where
x_center
and
y_center
are integers and their units are those of the pattern generator (for
the Gyrex : 10 micro-inches).
- -t x_trans y_trans
-
The masks are translated by
x_trans
in the x direction and
y_trans
in the y direction,
where
x_trans
and
y_trans
are integers and their units are those of the pattern generator (for
the Gyrex : 10 micro-inches).
EXAMPLE
Assuming that
infile
was produced by
ciftomann
for the Gyrex pattern generator, the command :
pggen -c 200000 200000 input_file
produces a set of masks from
input_file,
centering each mask at x = 2 inches, y = 2 inches.
FILES
- /dev/rmt4
-
The 800 bpi, no rewind after closing, tape drive.
- pg_write
-
The utility used to block, convert to EBCDIC, and do the
actual tape write.
