The latest revisions dont help, because they no more support the old FPGA devices. Helmut

I also have old versions of the Xilinx tools complete with dongle and programming cables. That's one of the reasons why I hate licenses. You may have everything you need, except if the PC is different you may need a new license file. That's the way it is with my current Lattice software. So far they have been happy to provide a license file for every new machine I've wanted to port the software to. But I am sure that one day that will no longer be the case and I'll be stuck! The first time I see a way to get away from these proprietary, licensed tools, I'm gone in a flash! Rick

I see they were > bought by Mentor. Yes, Mentor bought them some time ago and I believe it is still a product, but with a different name. Everyone still uses schematics for board level design, so the tools will always be there. Although to a large extent, even schematics are really just pin lists. When I plop an FPGA on the drawing page I am treating it like a pin connection list tying each pin (with its pin name) to a short net with its net name. The other end of the connection is almost always on a different page with the same net name/pin name connection list. The fact that the pin names are inside a box and have numbers doesn't really make it anything much different from a pin connection table. I wonder how long it will be before we give up on schematics altogether and just write pin lists or net lists? The only real advantage to a schematic from what I have seen is that our minds are pretty good at remembering things like orientation around a dial. So the component box becomes a watch face, if you will, and we can more easily remember that signal foo is in the upper right hand corner than we can remember that it is two thirds down in the pin list.
