All,

During the last meeting, the IBIS Open Forum suggested that BUG68 should be
considered pending until the sensitivity of the parser in detecting small
voltage differences in I-V curves can be checked (recall that BUG68
identified a problem with parsing I-V curve data where two successive lines
containing the same current points used slightly different voltage points).

By experimenting on the original BUG68 IBIS model using a PC running Windows
2000, I find that the parser must "see" a difference of at least 1e-5 volts
to classify two I-V curve data lines as different. The results were the
same on an HP UNIX system.

An updated version of the IBIS model, with the critical lines highlighted,
is enclosed.
