This looks like an Eldo netlist parsing error, not EZwave.
Difficult to determine the cause of the error without investigating the netlist file. It could be a mismatch between the name of a subcircuit and an instance.
Thanks for pointing out the wrong problem that we have been focusing so far.
Now we have solved the problem, we noticed that a warning which is telling one of our component name starts with "INV" is in conflict with the name of a built-in component. After we changed the name of that component, the problem has been solved automatically.
