To make a stimulus model as reusable as possible, we recommend that you create a testbench in which you instantiate the task you wish to simulate and connect it to a 'Stimulus' component. You can then write code in the stimulus component that exercises the inputs and outputs of your task.
You should connect your task to the stimulus component using its channels. You are free to write code to drive the signals of these channels yourself, but you can also use VHDL functions and procedures available in the package diamond_pkg compiled in the library diamond. This package can be found in <3L>Diamond\edition\Sundance\Xilinx\common\Simulation
