前言
看了那么久的verilog代码和文档，但还是没怎么接触过Vortex GPGPU全流程跑通与功能模块的波形显示。这一节就开始尝试探索这块内容。
一、跟着官方文档走一遍
已经有博客做了流程尝试，看了是通过容器保存运行环境的，我呢，还是老老实实按照流程走！
主要还是参考这个文档：https://github.com/vortexgpgpu/vortex/blob/master/docs/install_vortex.md
我用的是ubuntu18.04镜像，能在vmware上跑通，但还是有些坑点（苦，用了一晚上从vmware开始搭建环境搭完测试例子，很久没接触了，一堆坑，果然代理还是有必要的），我在下面注释中会提到：
# step 1. 安装依赖
sudo apt-get install build-essential zlib1g-dev libtinfo-dev libncurses5 uuid-dev libboost-serialization-dev libpng-dev libhwloc-dev
# step 2. 升级到g++-11和gcc-11
# 展开一下，ubuntu18.04默认的gcc和g++版本是7.4，没有11的ppa源，因此只能在添加ppa源以后再进行安装
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update & upgrade
sudo apt install gcc-11 g++-11
# 随后修改gcc和g++运行版本
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-11 11
# step 3. 下载vortex gpgpu包
git clone --depth=1 --recursive https://github.com/vortexgpgpu/vortex.git
# 多提一嘴，这个步骤有点麻烦，国内下载速度慢
# 我用了proxychains4和socks5通过主机代理加速下载，具体怎么配合不能说太多，我贴个链接
# https://blog.csdn.net/weixin_48915167/article/details/136705698
# 加速器方案自个儿确定
# 在有proxychains4的情况下，使用
proxychains4 git clone --depth=1 --recursive https://github.com/vortexgpgpu/vortex.git
# 可以加速下载
# step4. build vortex
cd vortex
mkdir -p build
cd build
../configure --xlen=32 --tooldir=$HOME/tools
#./ci/toolchain_install.sh --all # 这一步略麻烦，需要下载包，否则不太能成功，建议改为如下：
proxychains4 ./ci/toolchain_install.sh --all
source ./ci/toolchain_env.sh
make -s
# 至此环境搭建完毕
# step 5. 跑一个简单例子——Quick demo running vecadd OpenCL kernel on 2 cores
./ci/blackbox.sh --cores=2 --app=vecadd
跟官网大差不大，差异点只在于国内下载包速度不快而加了proxychains4（快到起飞）以及为gcc/g++升级而多做的事儿！
step 5跑完的结果如下：
root@ubuntu:/home/dention/vortex/vortex/build# ./ci/blackbox.sh --cores=2 --app=vecadd

官网的其他md还有一些测试例子，不举例了。但总结下来会发现，这些都是系统层面测试的例子（看结果出现了系统profiler的常见类型的结果），后面可能有探索的必要，先赊账。
目前先看verilog子模块的功能实现。
二、cache子模块的波形仿真
这个没啥.md文件当作参考了，只能看看unittest中有无线索。看一下文件结构：
root@ubuntu:/home/dention/vortex/vortex/hw/unittest# tree

2.1 必要的文件内容解释
主文件下的Makefile定义了项目的构建目标（如all、clean、run等）和一些特定的构建规则，通常包含了项目的构建逻辑，并且会调用其他Makefile或mk文件来包含共用的构建规则。其内容：
all:
$(MAKE) -C cache
$(MAKE) -C generic_queue
$(MAKE) -C mem_streamer
$(MAKE) -C cache_top
$(MAKE) -C core_top
$(MAKE) -C issue_top
run:
$(MAKE) -C cache run
$(MAKE) -C generic_queue run
$(MAKE) -C mem_streamer run
$(MAKE) -C cache_top run
$(MAKE) -C core_top run
$(MAKE) -C issue_top run
clean:
$(MAKE) -C cache clean
$(MAKE) -C generic_queue clean
$(MAKE) -C mem_streamer clean
$(MAKE) -C cache_top clean
$(MAKE) -C core_top clean
$(MAKE) -C issue_top clean
很符合一般的Makefile编写规则，这里的$(MAKE)表示这里的make规则应该有自定义部分。在Makefile中使用$(MAKE)而不是直接写make有几个好处：
1. 可移植性：如果需要在不同的构建系统或环境中使用Makefile，可以通过改变MAKE变量的值来适应不同的构建工具。
2. 灵活性：可以在Makefile中定义MAKE变量的值，例如添加特定的参数或选项，以控制make的行为。
(这部分参考kimichat的回答。kimichat，打广告费，>.<)
接下来看下主文件夹下的common.mk，带注释的代码如下：
# 设置默认的安装目录为当前目录
DESTDIR ?= .
# 配置和参数变量为空，可以在其他地方追加
CONFIGS +=
PARAMS +=
# 设置C++编译器标志
CXXFLAGS += -std=c++17 -Wall -Wextra -Wfatal-errors -Wno-array-bounds
# 启用位置无关代码生成，关闭某些警告
CXXFLAGS += -fPIC -Wno-maybe-uninitialized
# 添加配置标志
CXXFLAGS += $(CONFIGS)
# 链接器标志为空
LDFLAGS +=
# RTL包为空
RTL_PKGS +=
# RTL包含路径为空
RTL_INCLUDE +=
# 定义调试标志
DBG_FLAGS += -DDEBUG_LEVEL=$(DEBUG) -DVCD_OUTPUT $(DBG_TRACE_FLAGS)
# 定义Verilator的标志
VL_FLAGS = --exe
# 使用Verilog 2009标准，启用断言和所有警告
VL_FLAGS += --language 1800-2009 --assert -Wall -Wpedantic
# 禁用某些警告
VL_FLAGS += -Wno-DECLFILENAME -Wno-REDEFMACRO -Wno-GENUNNAMED
# 设置X初始化策略
VL_FLAGS += --x-initial unique --x-assign unique
# 定义模拟和SV DPI宏
VL_FLAGS += -DSIMULATION -DSV_DPI
# 添加配置和参数
VL_FLAGS += $(CONFIGS)
VL_FLAGS += $(PARAMS)
# 添加RTL包含路径
VL_FLAGS += $(RTL_INCLUDE)
# 添加RTL包
VL_FLAGS += $(RTL_PKGS)
# 指定顶层模块
VL_FLAGS += --cc $(TOP) --top-module $(TOP)
# 启用Verilator多线程模拟
THREADS ?= $(shell python -c 'import multiprocessing as mp; print(mp.cpu_count())')
VL_FLAGS += -j $(THREADS)
#VL_FLAGS += --threads $(THREADS) # 另一种多线程选项
# 调试配置
ifdef DEBUG
# 启用Verilator跟踪和结构跟踪
VL_FLAGS += --trace --trace-structs $(DBG_FLAGS)
# 添加调试信息和优化级别
CXXFLAGS += -g -O0 $(DBG_FLAGS)
else
# 定义NDEBUG宏
VL_FLAGS += -DNDEBUG
# 设置优化级别
CXXFLAGS += -O2 -DNDEBUG
endif
# 性能计数器配置
ifdef PERF
VL_FLAGS += -DPERF_ENABLE
CXXFLAGS += -DPERF_ENABLE
endif
# 默认目标，构建项目
all: $(DESTDIR)/$(PROJECT)
# 构建项目目标
$(DESTDIR)/$(PROJECT): $(SRCS)
# 使用Verilator构建项目
# $@ 是一个自动变量，它代表当前规则中的目标（target）文件名。当你在编写规则时，可以使用 $@ 来引用这个目标。
# $< 是一个自动变量，它代表当前规则中的第一个依赖（dependency）文件名。在规则中使用 $< 可以引用规则依赖列表中的第一个文件。
verilator --build $(VL_FLAGS) $^ -CFLAGS '$(CXXFLAGS)' -o ../$@
# 运行项目目标
run: $(DESTDIR)/$(PROJECT)
# 运行项目
$(DESTDIR)/$(PROJECT)
# 波形查看目标
waves: trace.vcd
# 使用GTKwave查看波形
gtkwave -o trace.vcd
# 清理目标
clean:
# 清理构建产物
rm -rf *.vcd obj_dir $(DESTDIR)/$(PROJECT)
所以需要在ubuntu下安装gtkwave和verilator。
接下来看下主文件夹下的cache子文件夹，如下：
root@ubuntu:/home/dention/vortex/vortex/hw/unittest/cache# tree
.
├── cachesim.cpp
├── cachesim.h
├── Makefile
├── ram.h
└── testbench.cpp
0 directories, 5 files
看一下这里的Makefile：
# 获取工程的根目录，即上两级目录的绝对路径
ROOT_DIR := $(realpath ../../..)
# 包含根目录下的配置文件
include $(ROOT_DIR)/config.mk
# 定义项目名称
PROJECT := cache
# 定义RTL源代码目录
RTL_DIR := $(VORTEX_HOME)/hw/rtl
# 定义DPI源代码目录
DPI_DIR := $(VORTEX_HOME)/hw/dpi
# 定义单元测试源代码目录
SRC_DIR := $(VORTEX_HOME)/hw/unittest/$(PROJECT)
# 设置C++编译器标志，包括头文件的搜索路径
CXXFLAGS := -I$(SRC_DIR) -I$(VORTEX_HOME)/hw/unittest/common -I$(VORTEX_HOME)/sim/common
# 添加硬件源代码目录到头文件搜索路径
CXXFLAGS += -I$(ROOT_DIR)/hw
# 定义源文件列表
SRCS := $(DPI_DIR)/util_dpi.cpp
SRCS += $(SRC_DIR)/cachesim.cpp $(SRC_DIR)/testbench.cpp
# 定义调试跟踪标志
DBG_TRACE_FLAGS := -DDBG_TRACE_CACHE
# 定义RTL包路径
RTL_PKGS := $(RTL_DIR)/VX_gpu_pkg.sv
# 设置RTL代码的头文件搜索路径
RTL_INCLUDE := -I$(RTL_DIR) -I$(DPI_DIR) -I$(RTL_DIR)/libs
RTL_INCLUDE += -I$(RTL_DIR)/interfaces -I$(RTL_DIR)/mem -I$(RTL_DIR)/cache
# 定义顶层模块名称
TOP := VX_cache_top
# 包含通用构建规则和变量定义
include ../common.mk
每个子模块下的Makefile都include了common.mk和根目录下的config.mk，都用于配置编译选项和指定依赖。所以比较直观的是，这些约束都用于unittest主文件下的Makefile文件。我们为了方便，减少编译内容，将Makefile削减为：
all:
$(MAKE) -C cache
#$(MAKE) -C generic_queue
#$(MAKE) -C mem_streamer
#$(MAKE) -C cache_top
#$(MAKE) -C core_top
#$(MAKE) -C issue_top
run:
$(MAKE) -C cache run
#$(MAKE) -C generic_queue run
#$(MAKE) -C mem_streamer run
#$(MAKE) -C cache_top run
#$(MAKE) -C core_top run
#$(MAKE) -C issue_top run
clean:
$(MAKE) -C cache clean
#$(MAKE) -C generic_queue clean
#$(MAKE) -C mem_streamer clean
#$(MAKE) -C cache_top clean
#$(MAKE) -C core_top clean
#$(MAKE) -C issue_top clean
只仿真cache模块。
2.2 cache子模块波形仿真——目前环境没啥问题了，就vcd因为配置问题出不来
先在ubuntu安装gtkwave和verilator：
sudo apt-get install gtkwave verilator
改东西，先回到主目录：
root@ubuntu:/home/dention/vortex/vortex# tree -L 1
.
├── blackbox.simx.cache
├── build
├── ci
├── config.mk.in
├── configure
├── docs

├── LICENSE
├── Makefile.in
├── miscs
├── perf
├── README.md
├── runtime
├── sim
├── tests
└── third_party
11 directories, 6 files
修改俩文件名：
mv config.mk.in config.mk
mv Makefile.in Makefile
随后在./vortex/hw/unittest下运行makefile，报错：
root@ubuntu:/home/dention/vortex/vortex/hw/unittest# make all
make -C cache
make[1]: Entering directory '/home/dention/vortex/vortex/hw/unittest/cache'
make[1]: *** No rule to make target '@VORTEX_HOME@/hw/dpi/util_dpi.cpp', needed by 'cache'. Stop.
make[1]: Leaving directory '/home/dention/vortex/vortex/hw/unittest/cache'
Makefile:2: recipe for target 'all' failed
make: *** [all] Error 2
原因是DPI_DIR变量使用了$(VORTEX_HOME)，但错误信息显示@VORTEX_HOME@，这意味着 VORTEX_HOME没有被正确替换。接着改：
# 在cache目录下的Makefile中定义VORTEX_HOME
# 定义 VORTEX_HOME
VORTEX_HOME := $(ROOT_DIR)
# 测试一下路径
info-roots:
@echo "ROOT_DIR is set to $(ROOT_DIR)"
直接在cache子目录下运行make即可：
root@ubuntu:/home/dention/vortex/vortex/hw/unittest/cache# vim Makefile
root@ubuntu:/home/dention/vortex/vortex/hw/unittest/cache# make
ROOT_DIR is set to /home/dention/vortex/vortex
好了，没问题了，能找到！接着下一步！
make all
结果是：
root@ubuntu:/home/dention/vortex/vortex/hw/unittest# make all
make -C cache
make[1]: Entering directory '/home/dention/vortex/vortex/hw/unittest/cache'
ROOT_DIR is set to /home/dention/vortex/vortex
make[1]: Leaving directory '/home/dention/vortex/vortex/hw/unittest/cache'
#make -C generic_queue
#make -C mem_streamer
#make -C cache_top
#make -C core_top
#make -C issue_top
最起码不报错了，这一步应该输出不了什么东西！
接着运行make run：

make -C cache run

这里报错原因大概率就是verilator版本不对了，嗐，查一下已安装的verilator版本：

ok，接下来回到原版的common.mk文件，重新运行，还是出现报错：

错误信息显示编译过程中找不到文件VX_config.h，不过很简单用find命令确定一下是否存在：
find /home/<user_name>/vortex/vortex/ -name VX_config.h
我这边实际显示是：
/home/dention/vortex/vortex/build/hw/VX_config.h
那接下来很容易，就是.mk中指定该文件的地址，完整内容是：
DESTDIR ?= .

当然了，不出意外还是报错，不过幸运的是不是配置问题：

// This is an implementation of a MSHR for pipelined multi-banked cache.
// We allocate a free slot from the MSHR before processing a core request
// and release the slot when we get a cache hit. This ensure that we do not
// enter the cache bank pipeline when the MSHR is full.
// During a memory fill response, we initiate the replay sequence
// and dequeue all pending entries for the given cache line.
//
// Pending core requests stored in the MSHR are sorted by the order of
// arrival and are dequeued in the same order.
// Each entry has a next pointer to the next entry pending for the same cache line.
//
// During the fill operation, the MSHR will release the MSHR entry at fill_id
// which represents the first request in the pending list that initiated the memory fill.
//
// The dequeue operation directly follows the fill operation and will release
// all the subsequent entries linked to fill_id (pending the same cache line).
//
// During the allocation operation, the MSHR will allocate the next free slot
// for the incoming core request. We return the allocated slot id as well as
// the slot id of the previous entry for the same cache line. This is used to
// link the new entry to the pending list during finalization.
//
// The lookup operation is used to find all pending entries for a given cache line.
// This is used to by the cache bank to determine if a cache miss is already pending
// and therefore avoid issuing a memory fill request.
//
// The finalize operation is used to release the allocated MSHR entry if we had a hit.
// If we had a miss and finalize_pending is true, we link the allocated entry to
// its corresponding pending list (via finalize_prev).
//
// Warning: This MSHR implementation is strongly coupled with the bank pipeline
// and as such changes to either module requires careful evaluation.
//
// This architecture implements three pipeline stages:
// - Arbitration: cache bank arbitration before entering pipeline.
// fill and dequeue operations are executed at this stage.
// - stage 0: cache bank tag access stage.
// allocate and lookup operations are executed at this stage.
// - stage 1: cache bank tdatag access stage.
// finalize operation is executed at this stage.
