PGA(10.1) PGA(10.1)
NAME
pga - generate CDL pins format for large packages
SYNOPSIS
cda/pga pin_file
DESCRIPTION
Pga takes a list of pin names (in numerical order), one per
line, and generates a pin list suitable for cdmglob(10.1)
and friends. Each pin name may be optionally followed by a
tab and a single character smoke(10.1) pin type. Special
pin names are: VCC, VDD, VSS and GND. These are recognized
and generate the proper pin type. Unless specified, the
default pin type is 4, or bidirectional tri-state.
There are two other special names: NC, which denotes no con-
nect pins and --, which specifies a hole in the PGA. Com-
ments may be preceded by a '# '. Special commands (preceded
by a '! ') worth knowing about are: debug, map, clip, and
holes.
debug is useful for double checking your definition,
map mapfile maps the pins via a map file; a map file is a
1:1 mapping suitable for PGA adaptors. An example of a map
file that will reverse all the pins in a mysterious 5 pin
package is:
1 5
2 4
3 3
4 2
5 1
clip [v|g] tells pga to capitalize the appropriate plane
(suitable for clip).
holes counts holes (pins declared as --) as pins and there-
fore will generate more pins. Normally holes are ignored.
