All rights reserved. 7. Since scan test modifies flip flops that are already in the design to enable them to also act as scan cells, the impact of the test circuitry is relatively small, typically adding about only 1-5% to the total gate count. endobj It is a latch-based design used at IBM. When scan is false, the system should work in the normal mode. The use of metal fill to improve planarity and to manage electrochemical deposition (ECD), etch, lithography, stress effects, and rapid thermal annealing. We will use this with Tetramax. It is desired to run the scan shift at a lower frequency which must be dictated by the maximum permissible power dissipation within the chip. NBTI is a shift in threshold voltage with applied stress. The way the fault is targeted is changed randomly, as is the fill (bits that dont matter in terms of the fault being targeted) in the pattern set. Once the sequence is loaded, one clock pulse (also called the capture pulse) is allowed to excite the combinatorial logic block and the output is captured at the second flop. Complementary FET, a new type of vertical transistor. During scan-in, the data flows from the output of one flop to the scan-input of the next flop not unlike a shift register. The theory is that if the most critical timing paths can pass the tests, then all the other paths with longer slack times should have no timing problems. Scan (+Binary Scan) to Array feature addition? This approach starts with a standard stuck-at or transition pattern set targeting each potential defect in the design. This creates a situation where timing-related failures are a significant percentage of overall test failures. Tester time is a significant parameter in determining the cost of a semiconductor chip and cost of testing a chip may be as high as 50% of the total cost of the chip. The path delay model is also dynamic and performs at-speed tests on targeted timing critical paths.
