Putting Data on EDA Servers: 4-5
The example below shows the contents of the device 305299-A as it would appear
in the
/bay
dir
/dra/2brel/programs
directory:
caps% ls -l 305299-A.00
total 8
-rwxr-xr-x 1 jryan 3482 Jul 28 1998 305299.abl
-rwxr-xr-x 1 jryan 1686 Jul 28 1998 305299.jed
3.
Issue a PCN to update the BOM. (See Chapter 6.)
Scripts run by
cron
every 12 hours (at BNE) or by an EDA analyst twice a day and
on request (at BNW) examine the
programs
directories. If it is appropriate, they
extract the checksum and move it and the device file directory to the
/rel
area. See
Processing of the Programmable Parts Directory
on page B-2 for more details.
Providing Device Files for EPROM and Flash PROM Devices
Each .
rom
file is a binary image sized to match exactly the physical EPROM or
flash PROM device where it will reside. This type of file is compatible with the
Data I/O programmer choice 16 file type, Absolute Binary.
To provide device files for EPROMs and flash PROMs:
1.
Create the directory
part_no
.
nn
in the /bay
dir
/dra/2brel/programs
directory.
2.
In this directory, put the
part_no
.rom file.
The
process_part
cron
job will move the data to
/bay
dir
/dra/rel/programs
with a computed checksum. (See
Processing of the Programmable Parts
Directory
on page B-2 for the timing.)
Note:
The parts must be moved to
/rel
before you run
bn_bomprocess
in the next step.
3.
Run bn_bomprocess.
4.
Issue a PCN to update the BOM. (See Chapter 6.)
Note:
For special program files such as Actel or Lattice files, contact EDA to process their
programmed parts.
