VHDL is an acronym which stands for VHSIC (Very High Speed Integrated Circuits) Hardware Description Language.
VHDL Related discussions are normally taken to the usenet group comp.lang.vhdl This groups was formed with the following charter
"The newsgroup comp.lang.vhdl was created in January 1991. It's an international forum to discuss ALL topics related to the language VHDL which is currently defined by the IEEE Standard 1076/93. Included are language problems, tools that only support subsets etc. but NOT other languages such as Verilog HDL. This is not strict - if there is the need to discuss information exchange from EDIF to VHDL for example, this is a topic of the group. The group is unmoderated. Please think carefully before posting - it costs a lot of money! (Take a look into your LRM for example or try to search http://www.Deja.com/usenet - if you still cannot find the answer, post your question, but make sure, that other readers will get the point)."Other places to discuss design issues are the edaindia mailing list firstname.lastname@example.org and the VHDL section of the EDAIndia forum
