	Dan,

	Preparing for ICT involves two parts - you need the correct
	features on the assembled board (accessible test points) and
	you need to work out data transfer to the testing resource.

	The upcoming replacement for IPC-D-275 has worthy info on
	the testpoint features, but I forget its number and I sus-
	pect it's not released yet.

	The data transfer part of the problem is generally worked out
	by either your CAD system vendor or the front-end tools that
	your testing house uses.  This will require explicit knowledge
	of which tester is to be used.

	There are a host of engineering issues as well, the most vis-
	ible in design are the presence of soft-ties (pullup/pulldown)
	on all logical commits - no direct ties to planes for other
	than supply.

	Your best resource will almost certainly be the house that
	will eventually do the testing.  They will likely have some
	printed material for you.

	If I can help further, email me offline.

	Regards,
