What is RTL?

RTL stands for Register Transfer Level. It is a level of abstraction used in digital design and computer engineering to describe the behavior and functionality of a digital circuit or system.

In RTL design, a circuit is described in terms of the flow of data between registers. The behavior of the circuit is represented using a hardware description language (HDL) such as VHDL or Verilog. The description specifies how data is transferred from one register to another, how it is processed, and how control signals are generated to control the data flow and operations within the circuit.

What is the difference between RTL and CodAL?

RTL design is a general approach used to describe digital circuits at the register transfer level, while Codasip CodAL is a specific design methodology and language developed by Codasip for designing and customizing processor at architecture and microarchitecture level. Codasip CodAL focuses on the higher-level description of the processor architecture and microarchitecture and their implementation details, aiming to streamline the design process and enable efficient customization and verification. Finally, CodAL supports the software side of processors while RTL does not.
