Description

The Dynamic Table component outputs and repeats a custom value sequence which is imported from a file.

The value sequence is defined as a list of values. The component outputs a number from the list every simulation step. Once it reaches the end of the list, it starts from the beginning.

For the value sequence [0, 2, 3, 1, 5], the output would look like Figure 2.

Properties

Figure 4. Example of a .csv file for Dynamic Table
  • Dynamic table file
    • Import file with the sequence of values that will be generated. Files that are supported are .data, .csv, .tdms, and .h5.

    • For .csv, .tdms, and .h5 files, the first column should be named "Time" and each other column should be named matching a signal we want to reproduce.
    • When using the .data files, only single signals are supported. With all other file extensions, multiple signals are supported.

  • Execution rate
    • Type in the desired signal processing execution rate. This value must be compatible with other signal processing components of the same circuit: the value must be a multiple of the fastest execution rate in the circuit. There can be up to four different execution rates, but they must all be multiple of the basic simulation timestep. To specify the execution rate, you can use either decimal (e.g. 0.001) or exponential values (e.g. 1e-3) in seconds. Alternatively, you can type in ‘inherit’ in which case the component will be assigned execution rate based on the execution rate of the components it is receiving input from.

      For .csv, .tdms and .h5 files,execution rate will be set based on “Time” column of imported file.
