HDL (Hardware description Language) is the type of language used, Verilog/VHDL versus a non-HDL javascript. RTL (Register-transfer level) is a level of abstraction that you are writing in. The three levels I refer to are Behavioural, RTL, Gate-level.May 12, 2013 read more
RTL in the circuit design cycle. RTL is used in the logic design phase of the integrated circuit design cycle. An RTL description is usually converted to a gate-level description of the circuit by a logic synthesis tool. The synthesis results are then used by placement and routing tools to create a physical layout. read more
In simple terms RTL design or Register Transfer Level design is a method in which we can transfer data from one register to another. or Constructing a digital design using Combinational and Sequential circuits in HDL like Verilog or VHDL which can model logical and hardware operation. read more
RTL (Register-transfer level) is a level of abstraction that you are writing in. The three levels I refer to are Behavioural, RTL, Gate-level. Behavioral has the highest layer of abstraction which describes the overall behavior and is often not synthesizable, but is useful for verification. read more
