An alternative way to solve this is to formally prove that the RTL code and the netlist synthesized from it have exactly the same behavior in all (relevant) cases. This process is called formal equivalence checking and is a problem that is studied under the broader area of formal verification .
Design at the RTL level is typical practice in modern digital design. [1] Unlike in software compiler design, where the register-transfer level is an intermediate representation and at the lowest level, the RTL level is the usual input that circuit designers operate on.
Verilator is a very high speed open-source simulator that compiles Verilog to multithreaded C++/SystemC. Verilator previously required that testbench code be written as synthesizable RTL, or as a C++ or SystemC testbench, because Verilator did not support behavioral Verilog. These are now supported.

In computer science, register transfer language (RTL) is a kind of intermediate representation (IR) that is very close to assembly language, such as that which is used in a compiler. It is used to describe data flow at the register-transfer level of an architecture . [ 1 ]
OpenSPARC is an open-source hardware project, started in December 2005, for CPUs implementing the SPARC instruction architecture. The initial contribution to the project was Sun Microsystems' register-transfer level (RTL) Verilog code for a full 64-bit, 32-thread microprocessor, the UltraSPARC T1 processor.
Register Transfer Notation (or RTN) is a way of specifying the behavior of a digital synchronous circuit. [1] It is said to be a specification language for this reason. Register Transfer Languages (or RTL, where the L sometimes stands for Level of abstraction) are similar to Register Transfer Notation and used to describe much the same thing, however they are of a synthesizable format and more ...
The commonly used levels of abstraction are gate level, register-transfer level (RTL), and algorithmic level. While logic synthesis uses an RTL description of the design, high-level synthesis works at a higher level of abstraction, starting with an algorithmic description in a high-level language such as SystemC and ANSI C/C++. The designer ...
A bipolar transistor switch is the simplest RTL gate (inverter or NOT gate) implementing logical negation. [2] It consists of a common-emitter stage with a base resistor connected between the base and the input voltage source. The role of the base resistor is to expand the very small transistor input voltage range (about 0.7 V) to the logical ...
