XABEL 5.1 (BLIFOPTX) fails on Truth Table designs

Description

ERROR MESSAGE:

*** ABL2XNF: Error
ABL2XNF is terminating abnormally due to errors encountered in
the blifoptx.exe xffast.bl0 -o xfffast.bl1 -errlog err.err
subtool

No .err file gets created.

DESCRIPTION:

This can be caused by a bug in blifoptix . When there are designs that
have truth tables in which rows can not be optimized, blifoptx fails
with this error message.

Solution

The only work around is to enter the design as equations instead of
as a truth table.
