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.
