Developmentof theCompiler VCompiler93 for VHDL

To develop a compiler aimed at VHDL, the strategy of one pass scanning and prediction parsing are adopted in the syntax analysis. In the algorithm suitable for dealing with the VHLD grammar conflicts, various kinds of overloading and elabrations for the static level are put forward. VCompiler93 as is developed for VHDL'93 works normally and correctly, demonstrating that the course of solution taken is solid and validity of the algorithm used well proved.
