[RISCV] 发现一个可以看RISC-V CPU行为的开源项目

最近在浏览某大型程序员交友 网站的时候发现一个好玩的项目，介绍如下：
A small program that handles mie, msi, mti and trap interrupts and updates some global variables on interrupts.
重点是他下面还放了一张图:
在这里插入图片描述
能看到RISCV CSR的行为太酷啦！！！

下面一起setup一下，万一以后项目能用到呢。
写这篇博客的时候，我已经go through了一遍，所以下面我会用一种顶层设计的方法来介绍怎么setup。

$ sudo apt install gcc g++ build-essential pip

Spike RISC-V ISA Simulator

$ git clone https://github.com/five-embeddev/riscv-isa-sim.git -b vcd_trace
$ git submodule update --init
$ sudo apt-get install device-tree-compiler
$ mkdir build
$ cd build
$ ../configure --prefix=/tmp/riscv-isa-sim/__install
$ make
$ [sudo] make install

你可以在/tmp/riscv-isa-sim/__install/bin下找到spike

/tmp/riscv-isa-sim/__install/bin$ ./spike

gtkwave

$ sudo apt install meson gperf flex desktop-file-utils libgtk-3-dev libbz2-dev libjudy-dev libgirepository1.0-dev

升级meson到 > 1.0，ubuntu自带的是0.61.2版本，不能满足项目的编译要求

$ pip install --upgrade meson

Building GTKWave

$ git clone https://github.com/gtkwave/gtkwave.git
$ cd gtkwave
$ meson setup build
$ meson compile -C build

你可以在/tmp/gtkwave/build/src/helpers/下找到fst2vcd，在/tmp/gtkwave/build/src/下找到gtkwave，将在下面的riscv-scratchpad用到。

riscv-scratchpad

$ git clone https://github.com/five-embeddev/riscv-scratchpad.git
$ cd riscv-scratchpad/baremetal-vcd-trace
$ make -j$(nproc)
# 把run_sim.sh里SPIKE=改到你刚才编译出来spike的路径，比如：SPIKE=/tmp/riscv-isa-sim/__install/bin/spike
$ source ./run_sim.sh

这里执行完的log如下
