Whereas Verilog used a single, general-purpose always block to model different types of hardware structures, each of SystemVerilog's new blocks is intended to model a specific type of hardware, by imposing semantic restrictions to ensure that hardware described by the blocks matches the intended usage of the model. An HDL compiler or ...
In certain respects, SystemC deliberately mimics the hardware description languages VHDL and Verilog, but is more aptly described as a system-level modeling language. SystemC is applied to system-level modeling , architectural exploration, performance modeling, software development , functional verification , and high-level synthesis .
In December 2009, a technical subcommittee of Accellera — a standards organization in the electronic design automation (EDA) industry — voted to establish the UVM and decided to base this new standard on the Open Verification Methodology (OVM-2.1.1), [1] a verification methodology developed jointly in 2007 by Cadence Design Systems and Mentor Graphics.
The SystemRDL language, supported by the SPIRIT Consortium, was specifically designed to describe and implement a wide variety of control status registers.Using SystemRDL, developers can automatically generate and synchronize register views for specification, hardware design, software development, verification, and documentation.
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 ...
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-A was an all-analog subset of Verilog-AMS that was the project's first phase. There was considerable delay between the first Verilog-A language reference manual and the full Verilog-AMS , and in that time Verilog moved to the IEEE, leaving Verilog-AMS behind at Accellera .
Released under the GNU General Public License, Icarus Verilog is free software, an alternative to proprietary software like Cadence's Verilog-XL. As of release 0.9, Icarus is composed of a Verilog compiler (including a Verilog preprocessor) with support for plug-in backends, and a virtual machine that simulates the design.
