Liz Board 2
: for a 0.5 um test chip (November 1999)
Do not use this board. Use Liz Board 3 instead.
Robert found a problem with Liz Board 2 during his test.
Sergei refined the board design (grounding, routing, etc.)
and named it Liz Board 3. Liz Board 3 has the same shematic
and the same pad locations as Liz Board 2.
