1、前言

一生一芯预学习中需要安装5.008版本Verilator，通过git方式下载所需要版本。

2、步骤

1、Verilator官网中找到Git Quick Install；

代码：

Prerequisites:

sudo apt-get install git perl python3 make autoconf g++ flex bison ccache

sudo apt-get install libgoogle-perftools-dev numactl perl-doc

sudo apt-get install libfl2 # Ubuntu only (ignore if gives error)

sudo apt-get install libfl-dev # Ubuntu only (ignore if gives error)

sudo apt-get install zlibc zlib1g zlib1g-dev # Ubuntu only (ignore if gives error)

git clone https://github.com/verilator/verilator ### Only first time

Every time you need to build:

unsetenv VERILATOR_ROOT # For csh; ignore error if on bash

unset VERILATOR_ROOT # For bash

cd verilator

git pull # Make sure git repository is up-to-date

git tag # See what versions exist

#git checkout master # Use development branch (e.g. recent bug fixes)

#git checkout stable # Use most recent stable release

git checkout v5.008 # Switch to specified release version

autoconf # Create ./configure script

./configure # Configure and create Makefile

make -j nproc # Build Verilator itself (if error, try just 'make')

sudo make install

3 、查看版本

@ysyx:~/verilator$ verilator --version

Verilator 5.008 2023-03-04 rev v5.008

4、C++例子

C++例子 官方步骤非常详细。

5、编译可能出现与4.210不同的报错

解决办法：

sudo apt-get install help2man
