How do I run a Verilog code?


  1. Compile from source on Linux/Mac or in Cygwin on Windows. You will need make, autoconf, gcc, g++, flex, bison to compile (and maybe more depending on your system).
  2. Install on MacOS using Homebrew.
  3. Install on Ubuntu using aptitude.
  4. Example 1. Save this verilog code as hello.v.
  5. Example 2. Save the code below as alu.v.

Does Iverilog Support System Verilog?

CS 450/650 – Computer Architecture. This is an open source compiler (iverilog) and simulator (vvp). You need at least version 10.0 to compile System Verilog code. (Debian is only up to version 0.9.

Is Verilog software free?

Free Simulators Icarus Verilog : This is best Free Verilog simulator out there, it is simulation and synthesis tool. It operates as a compiler, compiling source code written in Verilog (IEEE-1364) into some target format. For batch simulation, the compiler can generate an intermediate form called vvp assembly.

What is Yosys?

Yosys is a framework for Verilog RTL synthesis. It currently has extensive Verilog-2005 support and provides a basic set of synthesis algorithms for various application domains.

How do I create a Verilog file?

Go to File→New→Design Files→Verilog HDL File. Enter the text below into the file and save in a file “fadd. v”. This implements a full adder with three inputs and two outputs.

What is Cocotb?

Cocotb is a library for digital logic verification in Python. Coroutine cosimulation testbench. Provides Python interface to control standard RTL simulators (Cadence, Questa, VCS, etc.) Offers an alternative to using Verilog/SystemVerilog/VHDL framework for verification.

What is Verilog code?

Verilog is a Hardware Description Language; a textual format for describing electronic circuits and systems. Applied to electronic design, Verilog is intended to be used for verification through simulation, for timing analysis, for test analysis (testability analysis and fault grading) and for logic synthesis.
