Wow, I've been using xst (and webpack, base-x, and foundation) for
years now and never once heard this. I've used it in over 20 designs,
including some moderately-high-end virtex-4 stuff, and never had the
slightest idea that I was using inferior tools.

Who makes these other synthesis tools? Are they expensive? Is this
what happens when you do all of your engineering at a university?

Very Interesting thread -

2 of the "other synthesis tools" are from Synplicity, and from Mentor
(precision RTL) , and it just so happens both are supplied with
Lattice ispLEVER tools - which offer a free d/l from the web -

sorry to hear that 250,000 Xilinx customers have been using an
inferior synthesis tool all this time, by Xilinx' own admission -

All of the vendors work hard to supply reliable toolsets to their
customer base - and judging from all the marketing foils on every
vendor website, they have the best choice-

So the keyword here is choice - try out the toolsets offered free from
each vendor website - all it'll cost is some bandwidth and disc space
