Building a Dynamic Lookup Table

Because all the values defining a Lookup Table must be constants, the definition of the table cannot change dynamically.

In some situations, however, you may need to change the definition of the table as a function of time. There are two ways to build dynamic lookup table logic:

• You can define multiple Lookup Table elements, and use if,then logic to switch between the different tables as a function of time; or

• You can use a vector to define a lookup table. GoldSim provides several array functions that allow you to interpolate into the entries in a vector. Since vector entries can change with time, this allows you to use this functionality to create a dynamic lookup table.
