All sites have to obey that flow, by whatever techniques the test system uses to make that happen. The test engineer should not have to get involved with specifying "how" the test syste does that. Usually. I'd expect each test system to implement a few "extensions" for how any local "tricks of the trade" can be controlled. Let me give an example of such a "trick of the trade" from a former company. Testers with a single sequencer can't run patterns with match on more than one site at a time, because the sites may start in different states. But it may be the case that a process will produce devices that do all come up in the same state. Or the test may be positioned after another that leaves all sites in a common state. So a multisite strategy could allow "run in parallel, expecting to pass if they all start the same, and to get a match timeout if they start differently. In the event of the match timeout, run sites one at a time." With such an option in how things are run, there was obviously a setting to force whether to try that method or not. Does anyone else support my view? Or disagree?

We will be using STIL for scan & bist testing multi-DUTs to the limits of the tester, power supplies and the mechanical limitations. I would be glad to discuss this further with the group when time permits on this topic.
