This problem has been observed in Exemplar designs when these
are written out with FMAPs and EQNs.

If you are using Exemplar, turning off EQNs and MAPs
when writing out XNF from Exemplar Leonardo 4.0.3 may
eliminate the problem, which is associated with mapping
constraints generated by Exemplar.

In general, the "Could not find a bel" error message is
relatively generic, and all occurrences of such errors should
be verified against the latest revision of the Map program.
If the error still appears when processing the design with
the latest version of the software, and the workarounds
documented in the solutions referencing this error
message does not eliminate the error, it should be reported
as a separate bug.

This problem will be fixed in the M1.4 release.

If you are using Exemplar Leonardo Synthesizer, another workaround is to write out xnf output with gates instead of EQNs and NOT to include mapping (set xnf_write_lut_binding FALSE, set xnf_write_clb_packing FALSE).
