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.
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.
Icarus Verilog *BSD, Linux, Mac: GPL-2.0-or-later: Verilog simulator Verilator: Posix: LGPL-3.0-only or Artistic-2.0: Verilator is the fastest free Verilog HDL simulator. It compiles synthesizable Verilog into cycle accurate C++ or SystemC code following 2-state synthesis (zero delay) semantics.
I am no Verilog Expert, and don't pretend to be one. It truelly sucks to see the simulators arranged alphabetically. "important" to the industry should be the main factor, and 'year entering market' should be the second. It really sucks to see Verilog-XL buried at the end of the list,
The gEDA project offers a mature suite of free software applications for electronics design, including schematic capture using gschem, attribute management gattrib, bill of materials (BOM) generation, netlisting into over 20 netlist formats (gnetlist), analog and digital simulation (ngspice, gnucap, Icarus Verilog, and GTKWave, and Printed ...
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 ...
Flow to HDL tools and methods convert flow-based system design into a hardware description language (HDL) such as VHDL or Verilog.Typically this is a method of creating designs for field-programmable gate array, application-specific integrated circuit prototyping and digital signal processing (DSP) design.
ModelSim is a multi-language environment by Siemens [1] (previously developed by Mentor Graphics, [2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. [3] [2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, [4] Xilinx ISE or Xilinx ...
