2D Lookup Table XY
SIMPLORER 6.0 — Manual 295
>>Basics>Tools>Characteristics
The 2D Lookup Table XY is used to describe nonlinear behavior different from the predefined
characteristics. To achieve a simple and universal embedding of characteristics for describing
nonlinear behavior of components, characteristics can also be given through XY data pairs. It
is possible to create data files with:
• the component dialog
• the DAY Post Processor, or
• a text editor.
The function LOOKUP(X,Y) provides the Y value of a given X value. LOOKUP(XY1.VAL,5) ->
Y value of the characteristic XY1 for the X value 5.
The X-Y assignment of current and voltage (as physical quantities) depends on the application
of characteristics in the simulation model. See also 3.4 “Characteristics in Simulation
Models” on page 55.
Dialog Settings
«Unit X-Axis»«Y-Axis»
Defines the units for X and Y Axis. The units are displayed in the column headings in the lookup
table and saved in the created .mdx file.
� «File Name»
If no file is used, enter the data-pairs in the table on the right side. Create, delete, or move
entries with the symbols placed on the upper right side. See also “Defining Parameters” on
page 49.
� «File Name»
To define the data points, a two-dimensional data file is used which can be created by the
DAY Post Processor or a text editor. The XY data file always has two channels (columns)
where X value and Y value are stored. The length (number of lines) of the data files is arbitrary.
To open or save files, click the symbols next to the text box. Please note: Select the correct
file filter (.mdx) before browsing. See also “The .mdx File Format” on page 467.
Click the button to display the 2D lookup table with the defined values. Please note: If you
use variables for the definition, the preview is empty.
