* Each folder consists of followings:
     1) 5 sets of 2X + DUT.  The 5 sets consist of 5 different via structure.
	 2) \DUT.  Device under test.
	 3) \2X_only. 2X through structure.
	   Under each 2X_only folder, there are 5 sets of 2X only.  Each corresponds to a different via structure.
	   To test de-embedding program flexibility, each 2X through structure contains 3 different lead-in traces of 95, 100, and 105ohm.
