将 make 与 Verilog 模拟器和 VPI 代码结合使用的最佳实践是什么

Question

我的第一个 VPI 项目已经进入了一些合理的阶段，该项目的目的是 帮助数字滤波器设计。不过目前我正在和伊卡洛斯一起工作 我也想测试 Verilator 和其他模拟器。

到目前为止，我有这个makefile，尽管这是为了构建C代码并且 一个简单的测试平台。我希望能够包含 makefile 并构建/模拟 不同的新 Verilog 项目。

我在网上没有找到太多 HDL 项目的 Makefile 示例。 我对我的实施在某种程度上感到非常满意并且可以继续下去 自己滚动，但希望看到任何组织良好的更大规模 项目。我还没有看过 OpenRISC 中的 Makefiles ...

我真正寻找的一个例子是 VPI testbench 项目，例如你 已经完成了您的 VPI 代码，现在想要围绕它构建一个小型生态系统 使用 Makefile 的层次结构。

假设我们只使用两个模拟器 - Icarus 和 Verilator。

Answer 1

这似乎是一个不同的基本 makefile。在我们的 makefile 中，我们通常有更多的目标，其中还包括综合、par 和模拟。遗憾的是，它们包含非常特定于供应商（Xilinx 和 Synopsys）的内容，这使得它不是很通用。而且我们通常有一个 makefile 的层次结构。我们有一个一般性的、一些模块细节，以及一些特定的子项目（例如内存系统）。

但如果你有兴趣，我在这里发布一个，让你印象一下它的样子：
