Verilog-2001 is a significant upgrade from Verilog-95. First, it adds explicit support for (2's complement) signed nets and variables. Previously, code authors had to perform signed operations using awkward bit-level manipulations (for example, the carry-out bit of a simple 8-bit addition required an explicit description of the Boolean algebra ...
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.
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 ...
Verilog-AMS is a derivative of the Verilog hardware description language that includes Analog and Mixed-Signal extensions (AMS) in order to define the behavior of analog and mixed-signal systems. It extends the event-based simulator loops of Verilog/ SystemVerilog / VHDL , by a continuous-time simulator, which solves the differential equations ...
Verilog-A is an industry standard modeling language for analog circuits. It is the continuous-time subset of Verilog-AMS. ... additional terms may apply.
In computer engineering, logic synthesis is a process by which an abstract specification of desired circuit behavior, typically at register transfer level (RTL), is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool.
The Verilog-AMS and VHDL-AMS languages are widely used to model logic behavior. Other modeling approaches ... additional terms may apply. By using this site, ...
Icarus Verilog is an implementation of the Verilog hardware description language compiler that generates netlists in the desired format and a simulator. It supports the 1995, 2001 and 2005 versions of the standard, portions of SystemVerilog , and some extensions.
