Just wanted to know as to how much the simulation run-times suffer
if OO mechanisms are implemented in VHDL. I know that C++ code is roughly
10 times slower than C code. Just wondering about VHDL innovations for system
design. No doubt OO will help system designers, but what about the run-times
of the simulators??

Thanks,
Deepu

  C++ compilers can do one of the following:

    .1) Translate C++ in C and compile the C.
    .2) Translate C++ in native code and assemble it.

  Either way, the runtime performance of the compiled application depends
upon the quality of the compiler.

  Now ... it can take longer to compile a C++ application - its a more
complicated task. That has nothing to due with application performance though.

  The performance will also degrade if use is made of RTTI or virual
functions, and careless inheritance and this, that, and the other.

  However well designed C++ code shouldn't be any slower than equivalent C.
