    Hi Syed:
    Let me add that when creating connection files careful attention
should be paid to the pin names of the mating connectors, in order to
determine if any swap files are required (which then needs to be
specified in the .con file). Furthermore, when carrying out multi-board
hierarchical simulation, it is advisable to create a Net file (,net) to
limit the system simulation only to those nets or buses of interest,
thereby enhancing the simulation efficiency. I have discovered that the
TMP program has some important limitations when executed in conjunction
with a Net file. However, ISF2XTK cooperates well with .net and
generates a Topology file containing only those nets dictated by the Net
