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.
Catapult C supports SystemC model generation intended for virtual platforms, and a SystemC test environment to verify the generated RTL against the original C++ using the original C++ testbench. Catapult C supports the synthesis of Transaction Level Models (TLM), including standard off-the-shelf bus interfaces and custom protocols.
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 ]
RTL is the earliest class of transistorized digital logic circuit; it was succeeded by diode–transistor logic (DTL) and transistor–transistor logic (TTL). RTL circuits were first constructed with discrete components, but in 1961 it became the first digital logic family to be produced as a monolithic integrated circuit.
Classes can be parameterized by type, providing the basic function of C++ templates. However, template specialization and function templates are not supported. SystemVerilog's polymorphism features are similar to those of C++: the programmer may specifically write a virtual function to have a derived class gain control of the function.

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 ...
