/* Region Number */ 2
Region Type
You can define three types of regions for each region number you have specified:
• STD defines the actual mask region.
• MARGIN_MAX defines the maximum margin area when test margins are set
to 100%.
• MARGIN_MIN defines the minimum margin area when test margins are set to
-100%.
Example to Region Type:
/* Region Type */ STD
/* Region Type */ MARGIN_MAX
or
/* Region Type */ MARGIN_MIN
Number of Vertices
The number of vertices is an integer that specifies the quantity of X and Y
coordinates needed to define a mask region or polygon.
Example to Number of Vertices:
/* Number of vertices */ 4
X and Y Coordinates
These are the floating-point numbers that define the locations of the mask polygon
vertices for each region and region type defined in the mask file. Mask Files use a
relative coordinate system based on an eye diagram’s zero level, one level, and
crossing point parameters.
Example to X and Y Coordinates:
+0.0, +1.0
Mask Setup
You can list various remote commands in the mask setup area to define the relative
vertical and horizontal positions of the 0 and 1 coordinates of the mask X and Y-
axes. Commands listed in the setup area are executed as part of the mask data
load process.
Example to Mask Setup:
:MTES:SCAL:YTRACK OFF
:MTES:SCAL:Y1 -0.65
:MTES:SCAL:Y2 +0.65
:MTES:SCAL:XDEL 312.5E-12
:MTES:AMET NRZEYE
