Shmoo plots play a vital role in debugging. These plots are helpful to nail down the electrical failures in a circuit under test. The patterns provided by DFT engineers are tested by the test-engineers under different process conditions and with …

2023年9月2日 · Shmoo测试是芯片测试中一种常用的技术手段，其方法是选取两个与芯片性能相关的指标，如最大工作频率与电源电压，分别在两个维度上对这两个指标进行扫描，并在X-Y的二维坐标系中对扫描的结果进行显示，从而可以比较直观地显现这两个被选取变量之间的相互关系。 测试的基本原理是 检查应用于芯片作为输入的二进制响应是否与输出的比较值相匹配。 如果响 …

2022年10月11日 · Sweeping a test condition parameter through a range and obtaining a plot of the results. In semiconductor testing, shmooing is the testing technique of sweeping a test condition parameter through a range to look at the device under test in operation as it would perform in the real world.

A Shmoo plot is a graphical representation of a series of measurements in which you measure e.g pass/fail characteristics while sweeping a number of variables.

With the IDS shmooPLOT tool, you can easily access the data you need to generate shmoo analysis charts such as: li>Boxplot per Line Shmoo - a one-dimensional, pattern-based line shmoo chart with boxplots displaying the distribution of first-fail or last-pass locations.

The Shmoo plot shows whether the device under test (DUT) passed or failed when various combinations of parameters are applied to the DUT. A Shmoo plot is a graphical representation of a series of measurements in which you measure e.g pass/fail characteristics while sweeping a number of variables.

What is Shmoo plot? Shmoo plot is a graphical display of the response of a component or system varying over a range of conditions or inputs.

2017年5月12日 · The shmoo plot is just the graphical representation of this matrix, possibly with each matrix cell weighted according to criteria to be defined by your (e.g. pass/fail if the cell's value is above or below a certain threshold).

Shmoo plots can be useful for graphically representing test results obtained when characterizing a part using two test variables. When testing a device, one may want to know how a device will …

The Shmoo plot will be illustrated by measuring the effect of power supply reduction on performance: Nominally, a DUT operates at 1 Volt Vdd with 25 ns delay. A set of test patterns is applied repeatedly to the DUT while sweeping:
