Control Table Extrapolation Regions
A region is an area that defines locally where to extrapolate before globally extrapolating over the entire table.
For example, consider filling a large table that has twenty breakpoints for each normalizer by extrapolation. Two problems arise:
To have meaningful results, set values at many operating points.
To set values at many operating points takes a long time.
To overcome this problem, you can:
Define regions within the lookup table.
In each region, set the values of some operating points.
Click
to fill the table by extrapolation.
Each region is filled by extrapolation in turn. Then the rest of the table is filled by extrapolation. The advantage of using regions is that you can have more meaningful results by setting values for a smaller number of operating points.
Cells are colored:
Blue with rounded corners if they form part of the extrapolation mask
Purple background if they are part of a region
Both if they are part of the extrapolation mask and part of a region.
Define a Region
Click and drag to highlight the rectangle of cells in your tradeoff table.
To define the region, click
in the toolbar, or right-click and select Regions > Add to Region, or select the menu option Tables > Regions > Add to Region.
The cells in the region are colored with purple backgrounds.
Clear a Region
Highlight the rectangle of cells in your table.
To clear the region, click
in the toolbar, or right-click and select Regions > Remove from Region, or select the menu option Tables > Regions > Remove from Region.You can clear all regions at once by selecting Regions > Clear Regions.
