In the distant path, I had the select lines (the heavy loads that
cross the data path and select things for it to do) captured at
the other end of the data path with a skewable scan clock so we
could (essentially) see the timing of the select lines after
crossing the data path. This made it possible to use the scan
path as an oscilloscope.

Was that the AMD with the 6 phase clock you mentioned before?
I was wondering about how boundary scan would work with that.
I suppose you'd have 6 separate scan paths to capture each
phases logic states.

All you need is a skew generator--which could be external
(i.e., tester).
