如何将多个 VUnit run.py 文件合并到单个 VUnit 运行中? [英] How to combine multiple VUnit run.py files into a single VUnit run?

问题描述

我有一个这样的目录和文件结构:

I have a directory and file structure like this:

vunit_multi/
    alfa/
        run.py
        ...
    bravo/
        run.py
        ...

VUnit run.py 可以单独运行.

The VUnit run.py can run separately.

有什么好的方法可以将这些多个单独的 VUnit 运行组合成一个带有组合状态报告的运行吗?

Is there any nice way to combine these multiple separate VUnit runs into a single run with a combined status report?

推荐答案

假设你的 alfa 和 bravo 运行脚本看起来像这样

Let's say your alfa and bravo run scripts looks something like this

from os.path import join, dirname
from vunit import VUnit

prj = VUnit.from_argv()

root = dirname(__file__)
lib = prj.add_library("alfa_lib")
lib.add_source_files(join(root, "*.vhd"))

prj.main()

现在安排你的脚本

from os.path import join, dirname
from vunit import VUnit

def create_test_suite(prj):
    root = dirname(__file__)
    lib = prj.add_library("alfa_lib")
    lib.add_source_files(join(root, "*.vhd"))

if __name__ == '__main__':
    prj = VUnit.from_argv()
    create_test_suite(prj)
    prj.main()

底部的 if 语句意味着如果文件作为脚本调用(因此您仍然可以使用它来测试 alfa)，则执行最后三行，但如果文件作为模块导入另一个脚本，则不会执行.

The if statement at the bottom means that the last three lines are executed if the file is called as a script (so you can still use it to test alfa) but not if the file is imported as a module into another script.

现在在顶级目录(vunit_multi)中放置一个像这样的新运行脚本

Now put a new run script like this in the top-level directory (vunit_multi)

from os.path import join, dirname
from vunit import VUnit
from glob import glob
import imp

def create_test_suites(prj):
    root = dirname(__file__)
    run_scripts = glob(join(root, "*", "run.py"))

    for run_script in run_scripts:
        file_handle, path_name, description = imp.find_module("run", [dirname(run_script)])
        run = imp.load_module("run", file_handle, path_name, description)
        run.create_test_suite(prj)
        file_handle.close()

prj = VUnit.from_argv()
create_test_suites(prj)
prj.main()

create_test_suites 将查找所有运行脚本，然后遍历这些脚本.每个脚本文件都将作为模块导入以访问 create_test_suite 函数.使用在此顶级脚本中创建的 prj 调用该函数，以添加为模块指定的库和文件.

create_test_suites will find all run scripts and then iterate over those scripts. Each script file will be imported as a module to get access to the create_test_suite function. The function is called with the prj created in this top-level script to add the libraries and files specified for the module.

现在，如果您运行顶级脚本，它将看到所有模块测试平台.

Now if you run the top-level script it will see all module testbenches.

注意:您可以使用比 imp 更新的模块，但 imp 也适用于较旧的 Python 版本.

Note: There are newer modules than imp that you can use but imp also works in older Python versions.
