Certainly a classic, but these days you can really bootstrap
your toolchain in a cleanroom quite quickly.

See e.g. http://www.excamera.com/sphinx/fpga-j1.html
which is fundamentally not safe from attacks like
http://www.h-online.com/security/news/item/Backdoor-found-in-popular-FPGA-chip-1585579.html
but it's hard to see how you could get something in
there in a tight, human-inspectable compilate, and 
use the FPGA as a sacrificial bootstrap step only.
