You may be right in that the problem is caused by your large
.tr0 file size. We have had a problem opening .tr0 files that
just might be your problem as well. To verify the problem the
.tr0 file must be written out in ascii rather than in
binary format. I believe the options below will do this.


Sometimes (with larger rather than smaller files) HSPICE adds
an extra character at the end of one of the first few lines
of data (the data immediately follows the curve names). Just
do a 'more' on the file and look for this character to see
if it is your problem. If so, a little script like the
one below will patch up the file. Avanti is aware of this
bug, by the way.

#!/bin/csh -f
awk '{print(substr($0,1,72))}' $1 > aaafixed.tr0
