You might look at:

      "A Set of Tools for VHDL Design" by Peter B. Reintjes
        in "Logic Programming: Proceedings of the Eighth International Conference",
pp 548-562, MIT Press, 1991

To quote from the abstract: "... The Prolog programs are of comparable
speed and the source code is at least an order-of-magnitude smaller
than other VHDL implementations." The paper discusses a VHDL parser,
query system, pretty printer, compiler, incremental compiler and a
logic synthesis system.

The classic reference for using Prolog for compiling in general is:

      "Logic Programming and Compiler Writing" by D.H.D. Warren,
      in "Software - Practice and Experience", Vol 10, #2, pp 97-125,
      John Wiley and Sons, 1980
