Register transfer level description (RTL), also called register transfer logic is a description of a digital electronic circuit in terms of data flow between registers, which store information between clock cycles in a digital circuit. The RTL description specifies what and where this information is stored and how it is passed through the circuit during its operation.
RTL design is the design of an RTL description of a system. The term is also used synonymously with "RTL description".
RTL is used in the logic design phase of the IC design cycle.
Logic simulator tools may verify the correctness of the design by simulating its functionality using its RTL description, among other things.
Logic synthesis tools may be used to automatically convert the RTL description of a digital system into a gate level description of the system.
