We are in the process of reworking an old design that used a Lattice ispLSI1032 CPLD. Unfortunately we no longer have any source files. All we have is a JEDEC file that we currently use to program CPLDs.
We contacted Lattice to ask about moving from the older design in to a newer CPLD and they said without any source files it would be impossible. So we are researching if anyone has ideas for a solution to reverse engineer the CPLD in to either a schematic or new source files/code.
Please review the attached JEDEC file. Any and all input or ideas are welcome, and any viable leads or assistance will be rewarded.
Please ask if there are any questions. Thanks!
