Thanks for your information, I sent an e-mail to lattice, but they still sleeping in America while I'm start working in europe.
The easiest way would be to get a program which convert my JEDEC file that it fits in the E - device. If this fails, I have to go back to the source code, recompile it and have to validate the design again. Since this is an old design, I sooner see the dentist than doing this. In this case, I would like to ask you again for the design expert type and version . I don't want to rework the JEDEC file, but hoped that only a device number or so is to be changed and not the fuse map.

Lattice changed their programming method from a proprietory system to JTAG about five years ago (perhaps more). As far as I know they still support the non-E variants of the 1000 series, at least is there in the V3.0 of their ISP document that I have. That came with a recent programmer. I know they also support both programming methods on all but their newest chips. My V8.4 of Lattice Design Expert still supports the 1016. I can't see what use Protel would be in this? Its true that it does have a built in CUPL programming language with a schematic front end. (not that i've ever used it, ABLE and VHDL cover all my needs). Protel though still won't turn your JEDEC file back into a logical drawing. The ISPLSI 1016 is the simplest isp device that lattice made (before they bought AMD's/Vantis's PLDs), it might be posible (with patience) to turn the download file back into a logical description of the function of the device. I believe that lattice publish the 'fuse map' format for the devices, the only task is to reference that back to the resources in the chip. Or depending what the design does, can you re-draw/write it? Design Expert is FREE, its much better to have the design files rather than just the jedec. Good Luck, Jason. -----Original Message----- From: Georg Beckmann [mailto:[EMAIL PROTECTED]] Sent: 17 January 2002 06:49 To: 'Protel EDA Forum' Subject: [PEDA] Lattice pld Sorry, if this is a bit off topic, I have to program iSPLSI 1016 devices from lattice. The design was made long ago ( 1993 ) and I have a valid jed - file. Lattice sells only the update of the iSPLSI 1016 called iSPLSI 1016E. My programmer detects a wrong device and can't program it. So I tried to use the in circuit feature to program it, but the same. The devices must have a different signature so that the jedec cannot be used. If ever possible, I don't want to go back to the source files and start all over again in a design process. If I have to do so, is it possible with the protel PLD part ?
