Default constructors do not take any arguments and have no parameters. However, it is possible to pass arguments to the constructors and Vitis Model Composer supports importing the class kernels with parameterized constructors. Both scalar and vector arguments can be passed to constructors. You can assign values to these parameters from the Kernel Class tab in the AI Engine Class Kernel block as shown in the following figure. You can also observe the parameterized constructor declaration in Kernel Class Constructor Variant section.
If you have multiple variants of Kernel Class Constructors, you can choose one of them and pass values to the constructor arguments accordingly.
