In reply to dave_59:
Dave, I know this is a bit old post, but Google popped it up, so I think others may run into this one as well.
What I have pulled out of the spec is that the bind does not “exist” in the scope of the code that you write it in, but is “bound” or “placed” in the scope of the bind_target_instance. Thus, when it goes to “find” the parameter, it will not see it. That was what the OP was running into.
It is like the statement is in 2 parts, the one that controls the bind “where” (type/instance etc) and the part for “what” (module/interface/program/checker) including identifier, parameters, and arguments.
Actually about to try this concept out to get around this error. Please do comment if my understanding seems correct.
