What Is Test Bench
The term has its roots in the testing of electronic devices where an engineer would sit at a lab bench with tools for measurement and manipulation such as oscilloscopes multimeters soldering irons wire cutters and so on and.
What is test bench. A test bench is hdl code that allows you to provide a documented repeatable set of stimuli that is portable across different simulators. The biggest benefit of this is that you can actually inspect every signal that is in your design. Test benches are used to simulate your design without the need of any physical hardware.
A testbench is simply a verilog module. One such system is the type of build we use at maximum pc hq for testing hardware known as the open air test bench. A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model.

Simulation allows you the ability to look at your fpga or asic design and ensure that it does what you expect it to.
Simulation is a critical step when designing your code. Mechanics did a bench test on the fuel control unit and found that it was mis rigged. A testbench provides the stimulus that drives the simulation.
Or n the critical evaluation of a new or repaired component device apparatus etc prior to installation to ensure that it is in perfect condition collins. Testbenches are pieces of code that are used during fpga or asic simulation. Bench test international dentist what to practice.
Whereas a testbench module need not be synthesizable. Since the dut s verilog code is what we use for planning our hardware it must be synthesizable. A test bench can be as simple as a file with clock and input data or a more complicated file that includes error checking file input and output and conditional testing.
But it is different from the verilog code we write for a dut.
