Test intellectual property trends, test issues and the wealth of owning test in-house

In a recent 1500 mile tour around various automotive companies in mainland Europe, I was amazed to find design engineers who had not heard of JTAG or boundary scan as a test technique. This paper introduces the IEEE 1149.1 standard, how it works, what you can do with it now - right up to examples of advanced use today. I will present some trends which will force any clear-thinking test department to look at JTAGpsilas benefits again, reinforce the importance of designing for test.
