VHDL Testbench Tutorial
VHDL Testbench is important part of VHDL design to check the functionality of Design through simulation waveform. Testbench provide stimulus for design under test DUT or Unit Under Test UUT to check the output result.
A test bench is HDL code that allows you to provide a documented, repeatable set of stimuli that is portable across different simulators. Testbench consist of entity without any IO ports, Design instantiated as component, clock input, and various stimulus inputs.
