Help converting JED to VHDL or ABEL

(1/1)

pablofg:
I recently read some old xc9536 chips that I wanted to modify. I could do this using ISE and Impact via JTAG.  I read the xc9536 in jed format and burnt it to different new xc9536 to check that the dump was good.

Now I'd like to modify the contents and add one or two things. Appartenly Xilinx or DATA I/O Abel is able to do that. I have been trying to find the software but it's nowhere to be downloaded. I found some version on archive.org inside some maganize CD that has an evalutaion version. Unfortunately this evaluation version does not support the xc9000 family and goes up to xc7000 only. Apparently the file that I need is called jed2abel.exe which seems to be there and work well, but it complains that it needs the .dev file for this family and I can't find it anywhere. I only need to convert 2 jed files to something that can be edited / understood and then I'll "compile" again using Impact / ISE 10.1, but I need those equations first. Can someone help me to find that library or could someone convert those files for me? Apparently only version 6 o ABEL supports that family.

Thanks in advance!

Small correction. The program seems to be JED2AHDL.EXE, someone has it or can do the conversion for me? V6 seems to be the right one.

Appears to be a .zip file here:  http://ebook.pldworld.com/_semiconductors/Atmel/Databook%20CDROM/Atmel/prod180.htm
search the page for 'jed2ahdl'

Hello @ak6dn

thanks for response.

I downloaded but this is what I get. What am I doing wrong? I guess that I need the right libraries for that device. Or should I type something different like xc9500 ?
I guess I need the .dev files, right?

You need a valid DataIO ABEL and/or SYNARIO installation as well that supports the devices you are using. This is just the disassembler program.
