Line 4: Often one 'knob' or variable is plotted on one axis against another knob or variable on another axis, producing a two dimensional graph. This allows the test engineer to visually observe the operating ranges of the device under test. This process of varying the conditions and inputs to the component or system may sometimes be referred to as 'shmooing' but more officially known as electrical testing or qualification. [[Automatic test equipment]] often contains software features that allow automated shmooing of a part. == Origin == The Schoo Plot was invented by VLSI Hall Of Fame inductee Robert Huston. == Etymology == Line 13 ⟶ 17: * [http://doi.ieeecomputersociety.org/10.1109/TEST.1996.557162 Shmoo Plotting: The Black Art of IC Testing] – a 1996 [[IEEE]] article by Keith Baker and Jos van Beers. * [http://i.cmpnet.com/eeproductcenter/memory/2006/03/chart1_032406.gif Example shmoo plot]. * [https://www.chiphistory.org/lg_vlsi_hall_of_fame.html#bhuston Shmoo Plot Inventor] [[Category:Plots]]
