GNU VHDL simulator

GHDL is the leading VHSIC Hardware Description Language (VHDL) simulator. Digital and mixed-signal systems such as field-programmable gate arrays and integrated circuits can be described by VHDL, and VHDL can also be used as a general purpose parallel programming language. GHDL compiles VHDL files and creates a binary which simulates the design. GHDL fully supports IEEE 1076-1987, IEEE 1-76-1993, IEEE 1076-2002 versions of VHDL, and partially IEEE 1076-2008.
