JTD, thanks for taking out some time to write that mail, but I'm afraid to
say that I couldn't understand a word of the following paragraph (which I is
the crux of your argument). Could you please try explaining it with a
different approach?

Consider a VHDL file that describes a PCI /AGP/USB/other device.

> for a particular expression of silicon + compiler.
