Mechanical Data
4-8: Putting Data on EDA Servers
Bay Networks makes an incoming
ftp
site,
wfltlink
(“Wellfleet link”) available to
its contract layout houses, which
ftp
Allegro layout files to it, in the form of .
tar.Z
files.
You can use
/dra/utils/get_pcb
to retrieve the PCB
tar
file from the layout house
and put it in an outgoing directory where a fab house can get to it via
ftp
.
To send layout files:
1.
Run the
get_pcb
script.
This opens
wfltlink
for anonymous
ftp
from the directory
/incoming/mds
,
which is the destination where the layout house
ftp
’d the files. The script
displays the files available:
Retrieving file listing from ftp server.
119148-A_B.tar.Z
119252-A_C.tar.Z
Enter Raw Board Number (e.g., 301123-A):
Note:
The fab drawing is the same number of the raw board. A panel drawing, if required, is the
last page in the fab drawing.
2.
Enter the board number, e.g., 119148-A, and the minor revision—
normally 00, but B for the directory sample listed above.
The script gets
Part_Rev
.tar.Z
via
ftp
from
wfltlink’s /incoming/mds
. It
uncompresses and untars it, deleting various files such as .
brd
, .
apt
, .
ld
, etc.,
and then runs
/dra/utils/zip
to create a
Part_Rev
.zip
output file, which it puts
on
wfltlink
, in a directory such as /
mfgdoc/pcb_aw78
.
3.
Tell your fab vendor to get the result via ftp from
wfltlink
to one of their
systems.
Putting Schematics in the /2brel/mech Directory
To support each PCB artwork revision, you need to send the PCB layout designer
a
schematic
.tel
or
schematic
.txt
file for each component, then, when the layout
work is done, you will likely back-annotate the schematic when you receive the
new files. Back annotation rearranges the reference descriptors after the board has
been laid out so they’re in a pattern and easier to find.
After you back annotate the board, and the annotation checks out with the new
netlist, you can put the schematic on the
/bay
dir
/dra/2brel/mech
area for release.
