Behavioral Code: By definition it defines the behavior of a digital component. It does not give information how it will be implemented into actual HW synthesis. It will not give information how registers and gates will be implemented to perform required operation. It is more like writing an algorithm or FSM in C. RTL: It is more precise form of a digital component. It gives information, how code will be implemented as actual HW after synthesis.
Also it gives information how data will be transferred between registers and gates. It's the same language, but different styles are used. With experience you can tell them apart quickly, here's a few traits of each:. Behavioural verilog code generally looks more like a sequential computer program running from top to bottom within an initial begin block.
Watch for delays between statements implemented using long simulation time waits e. Delays probably implemented by counting cycles of some particular clock. Note some Verilog system functions e. Code for synthesis tends to comprise many of independent 'processes' each with a sensitivity list. Some technologies do permit initial begin blocks for memory initialisation so again that is not a guarantee. Ultimately the designer knows the purpose of the code they write and will appropriately invoke it with the synthesis toolset or in a simulator.

Michael Albanian. Saeb AmirAhmadi Chomachar. Kiran K. What means Verilog netlist? Is it the same as gate level or it have a context base definition?
I'm confused because in some websites I don't know if they're saying 'this is a Verilog code that is using logic gates' or 'this is a Verilog code in gate-level' I will be very happy if somebody who wants to explain more details about this topic :.

With only as is: I'd call it structural; isn't often there only one module instance. Due to the module name test is implies this is a test harness which falls more in the behavioral definition. Behavioral level. RTL level don't have to be gate level , but primitive level. Not the best approach to design with Verilog, but would be OK for a teaching example.
