node voltages and be able to pick out one to plot without it taking a
long time? I don't know the answer, but it seems like a binary format
could have advantages there.
Like Werner, I've also wondered about hdf5 since there is a library
available for it and octave and I believe scilab both support it. My
weak understanding of hdf5 is that it would meet some of the
requirements for a simulator output file (you can write many variables a
sample at a time instead of .mat file where you write all the samples of
1 variable followed by all the samples of another). It also appears
that it would not nearly be enough to just say "hdf5" but you'd have to
further specify the file format.
In terms of commercial simulators, it is annoying as all get out that
they insist on wanting to use their own proprietary binary formats for
results because sometimes you really want to get the data into a
different tool. grrrrrr. This is clearly an area where geda can hands
down win just by documenting the file format used.
