I practice yoga because it helps with my flexibility. Of course, that’s a little like saying that lighting a candle helps with heating your house, but I digress. The point is, flexibility is generally a good thing, and that holds true for 3D ICs and their test strategies. As discussed in the Electrical Engineering Journal, a flexible 3D test strategy that uses a “plug-and-play” architecture allows multiple tests to use the same interface, simplifying the introduction and use of multiple tests. Structuring the architecture around the IJTAG standard also makes it easier to adjust to and adopt future test features. Having a test strategy you don’t have to bend over backwards to implement every time something changes? That’s true flexibility.
You’re creating chips with high functionality, multiple operating modes, low power consumption, and extreme reliability—pushing the manufacturing process to the limit. But your advanced ICs are increasingly sensitive to the smallest manufacturing variations, and that affects both performance and yield. Mentor's Foundry Solutions can help you solve your design challenges.
