The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off. After its acquisition by Cadence Design Systems, Verilog-XL changed very little over the years, retaining an interpreted language engine, and freezing language-support at Verilog-1995.
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 ...
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 ...
MyHDL [1] is a Python-based hardware description language (HDL).. Features of MyHDL include: The ability to generate VHDL and Verilog code from a MyHDL design. [2]The ability to generate a testbench (Conversion of test benches [3]) with test vectors in VHDL or Verilog, based on complex computations in Python.
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 .
A hardware verification language, or HVL, is a programming language used to verify the designs of electronic circuits written in a hardware description language.HVLs typically include features of a high-level programming language like C++ or Java as well as features for easy bit-level manipulation similar to those found in HDLs.
The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or a schematic design application that supports external simulators, such as KiCad or gEDA.
Physical design is based on a netlist which is the end result of the synthesis process. Synthesis converts the RTL design usually coded in VHDL or Verilog HDL to gate-level descriptions which the next set of tools can read/understand. This netlist contains information on the cells used, their interconnections, area used, and other details.
