Quick Answer

What is RTL?

RTL (Register-Transfer Level) is a hardware description that captures how data flows between registers on each clock cycle.

Definition

RTL is a modelling abstraction used in digital design. Engineers describe circuits at the register-transfer level in Verilog or VHDL, which is then synthesised into a gate-level netlist.
