At least where I work, there's no situation where we pay for multiple tools that do the same thing, it would be considered a waste of money to license multiple and I think I agree with that. The same goes for the synthesis and backend tools. Driving these tools is difficult to get right so we stick with just one. There would have be a really, really really compelling reason to switch and it's yet to manifest. Sure, the tools have bugs but we report them and they do get fixed. It would have to be something quite special to make a switch interesting, even more special than synthesiable VHDL 2008!
