 GHDL is not an interpreter: it generates machine code from your design,
 the only way for high speed simulation.
 
+GHDL fully supports IEEE 1076-1987, IEEE 1076-1993, IEE 1076-2002 and
+partially the 1076-2008 version of VHDL.

 Main features are:
 - available on Linux (x86 and x86-64), Windows and Mac OS x
-- fully support vhdl 1987, vhdl 1993 and many features of vhdl 2008
 - handle very large designs like leon3/grlib.
 - can write waveforms to a vcd or fst file.
 - partial support of PSL
 - support vunit (https://github.com/LarsAsplund/vunit)
 - support OSVVM (http://osvvm.org)
 - support cocotb (https://github.com/potentialventures/cocotb) through the VPI interface
