In order to simulate your specific design, you would need both the design under test, also known as DUT or the unit under test, also known as UUT along with the stimulus that has been provided by the test bench Singapore. It would be pertinent to mention here that the test bench has been a HDL code that would enable you to provide a documented and repeatable set of stimuli.
It would be portable across the different simulators. A test bench could deemed as a file having clock and input data along with a relatively complex file inclusive of conditional testing, error checking, and file input and output.
