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.
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.
Verilator is now used within academic research, open source projects and for commercial semiconductor development. It is part of the growing body of free electronic design automation (EDA) software. It is free and open-source software released under a GNU Lesser General Public License (LGPL) 3.0 only, or an Artistic License 2.0.
TINA software is available in installable and cloud-based versions. Feature versions exist for use in industry [6] and for educational use. [2] [7] TINA allows simulation, design, and real-time testing of hardware description language (HDL), such as VHDL, VHDL-AMS, Verilog, Verilog-A, Verilog-AMS, SystemVerilog and SystemC and for microcontroller (MCU) circuits, [2] as well as mixed electronic ...
OpenSPARC is an open-source hardware project, started in December 2005, for CPUs implementing the SPARC instruction architecture. The initial contribution to the project was Sun Microsystems' register-transfer level (RTL) Verilog code for a full 64-bit, 32-thread microprocessor, the UltraSPARC T1 processor.
The usage patterns, as well as the emphasis on RF design, were inspired by some commercial tools of the time. Later, support for other simulators has been added to cover VHDL, Verilog and SPICE engines to some extent. At this stage both devices and circuits were specific to the targeted simulator or specific versions thereof. [2]
This ambiguity is intentional. Wishbone is made to let designers combine several designs written in Verilog, VHDL or some other logic-description language for electronic design automation (EDA). Wishbone provides a standard way for designers to combine these hardware logic designs (called "cores"). Wishbone is defined to have 8, 16, 32, and 64 ...
