2) Folks like Joerg who realize that many a quarter IC can be replaced with
a five cent discrete circuit.
3) Those doing high-power designs where discrete devices still dominate.

I would imagine the IC guys do their "curve tracing" using a handful of FETs
(or whatever) on a test die being probed by something like a Cascade
Microtech probe station, a network analyzer, and fancy modeling software...
at that level everything is huge and expensive anyway.


4) A customer of mine used a curve tracer to check the connectivity
of signal lines to BGAs. Not for mass production, but for lab prototypes.
You can clearly see the protection diodes to vcc and gnd.
Removed a lot of doubt if sth. did not work as expected.
