It's hard to even buy a PC with less than 4 GB of memory which means
it has to have a 64 bit version of a Windows OS. If FPGA vendors
don't want to support 64 bit OS how can they expect customers to work
with their larger devices? I guess they just don't expect them to be
using the free versions of their tools. So they have to maintain two
completely different tool sets? I know the way the simulation vendors
sell tools with different levels of performance is to sell everyone
the same code and to turn on the "cripple" factor on the low end
tools. I would think the FPGA vendors would be providing the same
software to everyone and just using a license to enable the higher end
features of the paid for software. I guess they could turn off 64 bit
support too... but that would be too strange.

installed, Webpack will run just fine. You just have to modify the
install script, where it detects the 64-bit OS and exits, to comment out
the exit... Then it will install and just work without further problems.
Tested with Webpack 10.1 to 13.1 inclusive, on OpenSuse 11.0 to 11.4.
(I adopted OpenSuse because 11.0 offered to install the 32-bit libs and
simply worked, and I haven't looked back). Will probably work with most
other recent Linuxes (you may have to find/install a few libraries).

I'm running 64-bit Webpack v 13.1 on Windows 7.

I have ISE13.2, I believe the 64 bit webpack.

Well, the hardware supports 36 bit real addressing even in 32 bit
mode, though a single task can't address more than about 3GB.

The free versions don't support the larger devices. The line
keeps moving, though, and even small devices P&R faster with
more memory.

As far as I know, it is usually a compile time option to generate
the 32bit or 64bit instructions.
