Free Open-Source FPGA-Simulators: Cryptocurrency

Free Open-Source FPGA-Simulators

This is the Free Open-Source FPGA-Simulators, such as, SystemVerilog that is not a proprietary language and is free for personal use. I think what you mean is a free simulator that can compile and run SystemVerilog. Here’s that information:

  1. If working online is an option for you, check out It is an online IDE that gives you access to Synopsys VCS, Cadence Ncisive and other simulators.
  2. Download ModelSim PE Student Edition. It supports many, if not all SystemVerilog constructs.

List of Verilog simulators in alphabetical order
Simulator name License Author/company Supported languages Description
GPL Cver GPL Pragmatic C Software V1995, minimal V2001 This is a GPL open-source simulator. It is a pure simulator. This simulator is not fully IEEE 1364-2001 compliant. It does not support generate and constant functions. 
Icarus Verilog GPL2+ Stephen Williams V1995, V2001, V2005, limited SV2005/SV2009 Also known as iverilog. Good support for Verilog 2005, including generate statements and constant functions.
A. Bosio, G. Di Natale (LIRMM) V1995 LIFTING (LIRMM Fault Simulator) is an open-source simulator able to perform both logic and fault simulation for single/multiple stuck-at faults and single event upset (SEU) on digital circuits described in Verilog.
OSS CVC Perl style artistic license Tachyon Design Automation V2001, V2005 CVC is a Verilog HDL compiled simulator. CVC has the ability to simulate in either interpreted or compiled mode. Source code is available under a Perl style artistic license.
TkGate GPL2+ Jeffery P. Hansen V1995 Event driven digital circuit editor and simulator with tcl/tk GUI based on Verilog. Includes Verilog simulator Verga.
Verilator GPL3 Veripool Synthesizable V1995, V2001, V2005, SV2005, SV2009, SV2012, SV2017 This is a very high speed open-source simulator that compiles synthesizable Verilog to multithreaded C++/SystemC.
Verilog Behavioral Simulator (VBS) GPL Lay H. Tho and Jimen Ching V1995 Supports functions, tasks and module instantiation. Still lacks a lot of features, but this release has enough for a VLSI student to use and learn Verilog. Supports only behavioral constructs of Verilog and minimal simulation constructs such as 'initial' statements.
VeriWell GPL2 Elliot Mednick V1995 This simulator used to be commercial, but has recently become GPL open-source. Compliance with 1364 is not well documented. It is not fully compliant with IEEE 1364-1995.
ISOTEL Mixed Signal & Domain GPL ngspice and Yosys communities, and Isotel V2005 Open-source mixed signal ngspice simulator in combination with verilog synthesis software called Yosys and Isotel extension for embedded C/C++ (or other) co-simulation.
List of VHDL simulators in alphabetical order 

Simulator name License Author/company Supported languages Description
GHDL GPL2+ Tristan Gingold VHDL-1987, VHDL-1993, VHDL-2002, partial VHDL-2008 GHDL is a complete VHDL simulator, using the GCC technology.
Icarus Verilog GPL2+ Maciej SumiƄski Stephen Williams It supports the 1995, 2001 and 2005 versions of the standard, portions of SystemVerilog, and some extensions. VHDL preprocessor added that converts VHDL to Verilog
NVC GPL3 Nick Gasson VHDL-1993 NVC is a GPLv3 VHDL compiler and simulator aiming for IEEE 1076-2002 compliance. See these blog posts for background information. NVC has been successfully used to simulate several real-world designs.
YoSys GPL3 UnKnown Verilog-2005 design Yosys is a framework for Verilog RTL synthesis.
