Which free VHDL simulator can I use?

If you don't have a VHDL simulator yet, we would recommend the following simulators. You can download them free of charge.

Simulator	Download from	Windows	Linux	Mac OSX
Aldec Active-HDL, Student Edition	Aldec Download page	Yes	No	No
ModelSim Altera Starter Edition	Altera Quartus Web Edition	Yes	Yes	No
ISim	Xilinx Webpack	Yes	Yes	No
Simili	SymphonyEDA website	Yes	Yes	No
GHDL	GHDL website	Yes	Yes	Yes

We have not had great results with FreeHDL or with Green Mountain VHDL. It seems that these projects may have been terminated.
GHDL on Mac OSX uses Wine, but works without problems.
