Jedec file compare?

[Malcolm Reeves]

Hi,

Anyone know of a utility to compare jedec files (i.e. for pld etc.).
The only method I know of is to use a pld program to compare with an
existing pld which is not as convenient if you don't have the pld :-/.

TIA

There's the Unix/Linux diff utility. You can get a DOS version.

Acually if you are using windows/dos fc will work just fine. diff is
useful if you are going to use its output to modify a file but if you
just want an idication of the extent and approximate location of
differences fc will work just fine (and it already comes with the OS).

Hi Malcolm,

I use FolderMatch... http://www.foldermatch.com/fmnews.htm

It very nicely compares files, directories or drives.

I use it to synchronize all my PSpice and Client Project folders
between my main machine and my laptop.

It's US$35.

I used to use a form of diff that was included with XTree (DOS). One
problem I encountered was comparing a JEDEC file read from a chip with one
generated by a compiler. Many programs skip over blank portions (FF FF FF
FF ...) whereas the files read from the chips showed the entire fuse map.
So I needed a utility that could re-sync itself. No problem with files
generated from the same program.

JEDEC files are (mostly) just plain ASCII so any file compare utility
should work.
I use ExamDiff. It has some limited filtering capability for the
comparisons and it's FREE.

I should have said I have tried this and it doesn't work, at least
with the files Xlinix produces. The file does look to be ascii but it
has the compile date so that is one area of difference. Also, the
actually programming at the end looks a bit like an eprom hex file and
I'm guessing it is:

Start Address : program bytes : checksum
Start Address : program bytes : checksum
......

So depend on how many bytes the tool writes per line will give
completely different ascii file for exactly the same pld.

For a completely check I think it has to be a tool specifically for
jedec files, not just fc.

TIA

I tried to email you but apparently was unsuccessful.

I am the author of a family of true word-by-word file comparison tools
with keyword and phrase processing. They can be configured to handle
a variety of application specific requirements. I expect they will
handle the two problems you mentioned below. Because they are
word-by-word compares they can be configured to be insensitive
to most changes in text flow.

If you would like to email me a couple of sample files, I'd be happy
to see if I can process them.

Contact information, more detailed descriptions, and demonstration
versions of the Complite File Comparison Family are available
on my web page at:

http://world.std.com/~jdveale

Again I'd be happy to discuss this in more detail or tryout
some sample files.
