Roland -

Are you familiar with a company in the US called Intergraph? Here is a
site and info I read recently.
Please keep in touch. I am very interested in the work you are doing.

 6. Intergraph Corp. of Huntsville, Ala., is offering Solid Edge, its next-
  generation computer-aided design (CAD) software for mechanical assembly
  and part modeling. Solid Edge brings the performance of expensive,
  proprietary CAD systems to an open, easy-to-use, and cost-effective software
  architecture. The product is the result of Intergraph's advanced-capability
  Jupiter technology. Priced at $5,995, Solid Edge will be available for
  customer shipment by the end of 1995. Intergraph also announced support
  from 18 ASIC and FPGA vendors and 12 design consulting agencies for its
  VeriBest design software product line. The third release of the line is
  14.0 and includes non-linear delay modeling in the built-in static timing
  analysis for synthesis, VHDL synthesis, support of LPM 2.0.1, and integration
  with leading FPGA and ASIC implementation tools. VeriBest Synthesis is
  available now on Windows NT and SunOS starting at $24,000. VeriBest
  Simulator, available now for Windows NT, SunOS and HP/UX, begins at
  $15,000, with VeriBest Design Capture available for all supported operating
  systems at a starting price of $3,500.
