Chisel (an acronym for Constructing Hardware in a Scala Embedded Language [1]) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level. [2] [3] Chisel is based on Scala as a domain-specific language (DSL).

Microwatt is an open source soft processor core originally written in VHDL by Anton Blanchard at IBM, announced at the OpenPOWER Summit NA 2019 [2] and published on GitHub in August 2019. It adheres to the Power ISA 3.0 instruction set and can be run on FPGA boards , booting Linux , MicroPython and Zephyr .
In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, usually to design application-specific integrated circuits (ASICs) and to program field-programmable gate arrays (FPGAs).
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 world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
In the absence of a widely accepted open source hardware license, the components produced by the OpenCores initiative use several different software licenses.The most common is the GNU LGPL, which states that any modifications to a component must be shared with the community, while one can still use it together with proprietary components.
OpenRISC is a project to develop a series of open-source hardware based central processing units (CPUs) on established reduced instruction set computer (RISC) principles. It includes an instruction set architecture (ISA) using an open-source license.
