Sorry it was a mistake, I would write
Your modules have to be module A from ... to 19 and module B from 20 to
... and you have to place your *TBUF at x=16*.
...
Then it uses the TBUFs of column 16 and 18 in module A and the TBUFs in
column 20 and 22 in module B, and therefore it straddles the boundary.
You have to define a loc reference point in your B/M. All loc-statements
refer to this point. See my other posting from today, it contains an
example. There is "t0A_(0)" the reference point (line 22).
Bye Tom
