Parametric on-chip variation: A step towards accurate timing analysis
WEBAug 7, 2019 · To model these parameter variations, a few engineers came up with the on-chip variation (OCV) model. The concept of OCV was first introduced in technology nodes above 90nm. The fundamental idea behind OCV is to apply global derates on the whole design irrespective of the type of cells, its individual variation or its slew-load conditions.
Bimetallic Strip: Construction, Uses & Applications - EDN
WEBJul 27, 2020 · Introduction. According to Wikipedia, the basic invention of bimetallic strips comes from 18th-century clockmaker John Harris (1693-1776). Two strips of dissimilar metals are mechanically joined either by rivets or by being fused together along their length to form a structure that responds to changes of temperature by bending in …
Clock Domain Crossing Techniques & Synchronizers - EDN
WEBSep 30, 2014 · In general, a conventional two flip-flop synchronizer (2-FF) is used for synchronizing a single bit level signal. As shown in Figure 1 and Figure 2 , flip flop A and B1 are operating in asynchronous clock domain. There is probability that while sampling the input B1-d by flip flop B1 in CLK_B clock domain, output B1-q may go into metastable state.
Eye Diagram Basics: Reading, Analyzing and Applying
WEBDec 16, 2011 · An eye diagram is a common indicator of the quality of signals in high-speed digital transmissions. An oscilloscope generates an eye diagram by overlaying sweeps of different segments of a long data stream driven by a master clock. The triggering edge may be positive or negative, but the displayed pulse that appears after a delay period may go ...

Cross Sectional Area Of Wire: Formula & Calculation - EDN
WEBNov 15, 2016 · How to find the cross sectional area of a wire. First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.”. Thus, 0.001 inch = 1 mil, 0.01 inch = 10 mils and so forth. Then we define the cross sectional area simply as the square of the wire’s diameter in mils ...
