System Verilog is the first major HDL to offer object orientation and garbage collection. Using the proper subset of hardware description language, a program called a synthesizer, or logic synthesis tool , can infer hardware logic operations from the language statements and produce an equivalent netlist of generic hardware primitives [ jargon ...
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 .
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. SystemVerilog for verification uses extensive object-oriented programming techniques and is more closely related to Java than Verilog. These ...
Register-transfer-level abstraction is used in hardware description languages (HDLs) like Verilog and VHDL to create high-level representations of a circuit, from which lower-level representations and ultimately actual wiring can be derived. Design at the RTL level is typical practice in modern digital design.
High-level synthesis software can generally be used for the design of both application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs). Most high-level synthesis software is used to edit and verify code written in one of the mainstream hardware description languages (HDL) like VHDL or Verilog.
High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior.
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 ...
The level of effort required to debug and then verify the design is proportional to the maturity of the design. That is, early in the design's life, bugs and incorrect behavior are usually found quickly. As the design matures, the simulation will require more time and resources to run, and errors will take progressively longer to be found.
