It is unfortunate (at least for me) that the use of the Spartan-2000
precludes the use of the the web-pack tools from Xylinx. I'm sure that
the extra capacity will be welcome to those who can use it. I had been
planning to purchase a USRP2 system when they became available. But as
an individual unaffiliated with a university or a profit making
engineering firm, this appears to be unrealistic.

Way out of the question. I spend entirely foolish amounts of money on
such things already, but this would break the bank. With no prospect of
return, even I can't rationalize this.

60 days to conceive, implement, and debug - it can take 60 days to get
tools of this scale installed correctly.

Fat chance!

Not a viable option in my case.

An appealing idea, and it fits the community model well, but even if it
doesn't get the wind up the skirts of the legal types at Xylinx to have
their tools used in this way, I find it difficult to imagine how this
would not be cumbersome to the point of unusability.
Still hoping for an alternative...

Please note that the USRP2 uses a Spartan 3-2000 chip. This means that
if you intend to do your own FPGA development, you need to use the full
version of the Xilinx tools in order to generate an image for it. You
cannot use the free web pack version. Thus there are several options
for you:
- Just use the prebuilt FPGA images we provide
- Purchase the full version of ISE from Xilinx
- Get a 60 day demo version from the Xilinx Web Site
- Convince your Xilinx apps engineer to get you a free copy
- Universities often get the tools free of charge
- Release your changes to the community and we can find some sort of way
to build them for you (if anybody wants to work on putting together some
scripts to do this automatically, let me know).
