I find it a great tool as well. The true-to-spec support for the
VHDL-language is a strong point.
I've successfully used it on some medium size AMBA subsystems where the
stimuli generator had a lot of horrible things like unconstrained types.
At the time, the other low-cost simulators I tried all failed on that one.
The VCD-dump in conjunction with a tool like gtkwave is good enough for
most purposes. I haven't got around to trying the new patch for gtkwave
with VHDL types yet.
I also tried new wave format (ghw) and, apart of a bug (package wideI find it a great tool as well. The true-to-spec support for the

I use ghdl for many time of my job. Of course i use another simulator
(e.g modelsim) but I think it's time to promote ghdl as the first tool
for simulation and verification. As I said some days ago, with ghdl, it
is possible to recompile both altera and xilinx phisical libraries and
then simulate post synthesis core.The author ( Tristan Gingold) is very
careful to the feedback from users( bugs or suggestions).

I also tried new wave format (ghw) and, apart of a bug (package wide
signals) that led gtkwave to segfault, but now it's closed) it
works very well.
I encountered segfaults using ghw as well. Which versions of ghdl and
gtkwave fixed your problem?
BTW, count me in as a dedicated user of ghdl The project has made
impressive progress during the last two years. The integration in the
gcc suite enables instant line coverage reports using gcov.
Today ghdl 0.21 is out;
i'm already finished to compile xilinx Simprim
an Unisim libraries i can put here makefiles if anyone is interested.
