Hello,

Does anybody out there know, if there are plans to make an ANSI or C++
interface for CLSI's VTIP (SPI)? I've heard some rumors, but nothing seems
to be sure.
Background: We are using InterViews (a X11/C++ based graphic library) in
some projects but we are not planning to build an analyzer. Therefore it
would be very useful to use the CLSI software, but it's a lot of work to
produce a C++ interface (headerfiles) for SPI.

Another question related to this one: what will be the base to define a
standard of the intermediate VHDL representation - a concrete language as C
or ANSI C or something more abstract?

And another question: As far as I can see from systems available to us, it
seems not to be possible to build a set of basic libraries and simply use
them in several designs/places. To make it more clearly:
The lib/data managers of the systems need one directory where all the data of
a design must be stored, including basic libs as STD or basic cells.
On the other hand, I'd prefer separated environments/directories for each
design project. Disadvantages are:
1. The whole basic stuff has to be copied (and reanalyzed).
2. After copying the basic libs, they are stuff of the designer - updates to
   my base have no effect and they are no longer write protected.
(What I would like to have is something like -I and -L in C compilers.)
Is something like this planned - or is it impossible, because the data
management needs pointer like "used by"? Or am I wrong and there are systems
which do act in this way?

Thanks for answers
tom.
