In June 2006, VHDL Technical Committee of Accellera (delegated byIEEE to work on next update of the standard) approved so called Draft3.0 of VHDL-2006. While maintaining full compatibility with olderversions, this proposed standard provides numerous extensions that makewriting and managing VHDL code easier. Key changes includeincorporation of child standards (1164, 1076.2, 1076.3) into the main1076 standard, an extended set of operators, more flexible syntax of'case' and 'generate' statements, incorporation of VHPI (interface toC/C++ languages) and a subset of PSL (Property Specification Language).These changes should improve quality of synthesizable VHDL code, maketestbenches more flexible, and allow wider use of VHDL for system-leveldescriptions.

VHDL is a fairly general-purpose language, and it doesn't require asimulator on which to run the code. There are a lot of VHDL compilers,which build executable binaries. It can read and write files on thehost computer, so a VHDL program can be written that generates anotherVHDL program to be incorporated in the design being developed. Becauseof this general-purpose nature, it is possible to use VHDL to write a that verifies the functionality of the design using files on the hostcomputer to define stimuli, interacts with the user, and comparesresults with those expected. This is similar to the capabilities of the. VHDL is a language, and as a result is considered by some to be superior to Verilog. The superiority of one language over the other has been the subject of intense debate among developers,for a long time. Both languages make it relatively easy for aninexperienced developer to produce code that simulates successfully butthat cannot be synthesized into a real device, or is too large to bepracticable. One particular pitfall in both languages is the accidentalproduction of rather than as storage elements.
