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. In fact, in circuit synthesis, an intermediate language between the input register transfer level representation and the target netlist is sometimes ...
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems.It is most commonly used in the design and verification of digital circuits, with the highest level of abstraction being at the register-transfer level.
The concept of TLM first appears in system level language and modeling domain. [3] Transaction-level models are used for high-level synthesis of register-transfer level (RTL) models for a lower-level modelling and implementation of system components. RTL is usually represented by a hardware description language source code (e.g. VHDL, SystemC ...
SystemVerilog for register-transfer level (RTL) design is an extension of Verilog-2005; all features of that language are available in SystemVerilog. Therefore, Verilog is a subset of SystemVerilog. Therefore, Verilog is a subset of SystemVerilog.
A hardware description language looks much like a programming language such as C or ALGOL; it is a textual description consisting of expressions, statements and control structures. One important difference between most programming languages and HDLs is that HDLs explicitly include the notion of time.
Using high-level synthesis, also known as ESL synthesis, the allocation of work to clock cycles and across structural components, such as floating-point ALUs, is done by the compiler using an optimisation procedure, whereas with RTL logic synthesis (even from behavioural Verilog or VHDL, where a thread of execution can make multiple reads and ...
